networking options?

[Deadbot1]

I have a project in mind that requires I be able to determine the network connectivity of a host computer. Is it possible to use the USB port on a Teensy to do this and if so how? I would like the end result to be cross platform(Win,linux,Mac) if possible and completely self contained in the Teensy if possible.

My Ideal situation would be to have the Teensy be able to ping a set of IP addresses to determine if there is a web connection or not and perform actions based on this info.

Any ideas/info/direction would be greatly appreciated.

Currently there's no software for Teensy which implements USB networking protocols like CDC-ETH or RNDIS. I'm considering doing something like this someday, but it's still pretty far into the distant future.

Probably the best thing so far is SLIP over USB serial. The OSC library (formerly OSCuino) is probably the best place to start looking, since it uses that. Of course, it does require running a proxy program on the PC side.
