its been a long effort keeping at it! Check this out:
teensy host (T3.6) attached to an ESP8266, the code connects to a remote ESP not only to control the teensy, but, why stop there? let's control that teensy's ESP as well!
I created the dynamic ability to control both the ESP and TEENSY at the other end of the link. What does that mean? I can run UART data to teensy ports while running, ex, FASTLED stream on pin14 of the ESP attached to it.
This also entitles the user, to control the ESP in standalone mode, without the teensy attached to it, which, also frees up the endpoint communication uart protocol to allow controlling the esp's uart as well! I ran one of the uart display's off it yesturday! 
this is the video of the TEENSY attached to an ESP, controlling a standalone ESP with a led strip attached.

Also! I didn't stop there! I decided to also write transparency code for the local master teensy!
here is a WifiScan.ino demo, slightly modified at the top, the rest code running as is, flashed to teensy!
Code:
/*
* This sketch demonstrates how to scan WiFi networks.
* The API is almost the same as with the WiFi Shield library,
* the most obvious difference being the different file you need to include:
*/
// #include "ESP8266WiFi.h" <<---- DELETED !!
////////////// ADDED ///////////////
#include <teensywifi_controller.h>
teensywifi_controller WiFi = teensywifi_controller("WiFi", &Serial1, "192.168.2.168:80");
/////////////////////////////////////
void setup() {
Serial.begin(115200);
Serial1.begin(1000000); ///// <---------------- ADDED
// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("Setup done");
}
void loop() {
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0)
Serial.println("no networks found");
else
{
Serial.print(n);
Serial.println(" networks found");
for (int i = 0; i < n; ++i)
{
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(")");
Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE)?" ":"*");
delay(10);
}
}
Serial.println("");
// Wait a bit before scanning again
delay(5000);
}
Now, we open up teensy Serial monitor! what do we see!???

the video for the above code running on teensy is here: https://www.youtube.com/watch?v=oK2DiuyKvjA
Looks like a dual teensy&esp controller with transparency functions of the ESP on the Teensy!
But wait, theres more!
I've imported function control transparency to give the teensy additional use of the ESP.
Libraries I worked on and transferred control over to teensy:
ESP8266WiFiSTA.h
ESP8266WiFiScan.h
ESP8266WiFiMulti.h
ESP8266WiFiAP.h
ESP8266WiFiGeneric.h
ESP8266WiFiType.h
WiFiClient.h
WiFiUdp.h
Most of if not all of the functions can be ran as-is on teensy with the stock return values of the ESP. This gives the ability to connect to websites, send UDP packets (even listen for packets udp ex Udp.begin(8266) ).
using WifiMulti you have the addAP and run functions as well
heres quite a list of the functions i placed in the code to do all this!
Code:
// NATIVE ESP8266 TRANSPARENCY COMMANDS
virtual int availableForWrite();
virtual size_t peekBytes(uint8_t *buffer, size_t length);
size_t peekBytes(char *buffer, size_t length) {
return peekBytes((uint8_t *) buffer, length);
}
// STATUS AND LOCAL IP NEED SEPARATE SCOPE, 2 LIBRARIES USE THEM!
// ESP8266WIFISTA.H
// begin() --> shared with above functions

virtual int endPacket();

virtual IPAddress destinationIP();
// PEEK, WRITE BUF, WRITE, AVAILABLE, READ, READ BUF, FLUSH
there may be more implemented or not listed as sometimes i loose track, but the ones posted above definately run well.
Here is the compilation info for Teensy 3.6 for the library project im working on of WifiScan.ino demo that comes from ESP branch:
Code:
Sketch uses 148012 bytes (14%) of program storage space. Maximum is 1048576 bytes.
Global variables use 13184 bytes (5%) of dynamic memory, leaving 248960 bytes for local variables. Maximum is 262144 bytes.
Here is the current ESP compilation of the 2-way communication link i worked on, with both ends running at 1Megabaud uart rates for teensy <-> esp links:
Code:
Sketch uses 368807 bytes (35%) of program storage space. Maximum is 1044464 bytes.
Global variables use 39756 bytes (48%) of dynamic memory, leaving 42164 bytes for local variables. Maximum is 81920 bytes.
heres the video of the esp as standalone running the uart display controlled from a teensy 3.6 over IP, library supports serial writes and buffered writes, Ive demo'd the buffered writes to send the 6 byte payload including crc to the display which is fast
https://www.youtube.com/watch?v=cWpr6U_bRX8
here is the demo using single byte transmission over IP
https://www.youtube.com/watch?v=H0WUIRmC868
What I'd like to implement is, currently, it supports sending dynamic payloads to the teensy handler at other end of the link, I'd like to change that behaviour, or perhaps, overload the call with a reference instead. It's simple really, you could send a 400 byte payload buffer to your teensy at the other end of the link as a reference, the user can edit the array (perhaps with sensor values) and when the function exits, the array is returned back to the main teensy. single packet to send, single to receive, very efficient. storing sensor data in the buffer would be handy for remote monitoring purposes as the updated contents are returned.
current handler:
Code:
void hndl(const uint8_t *buf, size_t size) {
for ( uint16_t i = 0; i < size; i++ ) Serial.print((char)buf[i]); Serial.println();
}
when scope exits, library sends back an ACK to main teensy immediately.
but don't let this idea discourage you. Remember I said it was multi master? You can send your own payload from the OTHER end of the link to the IP of the intended master.
as per previously referenced video, shows both teensies connecting to each other and controlling each others leds using the same identical libraries on teensy, and identical code on both esps:

YOU decide where your data goes, no need to reflash a location if you need to change data paths
