Teensy 3.6 programming a Teensy, like arduino boards can? :-Silly sidetrack

So the Teensy 3.6 has USB Host capability.

Wonder if you could rig it so that you could Use a teensy to program another teensy via the Host interface.

And then, could you daisy chain multiple teensies to program the next teensy down the chain. And what if you use the last Teensy to program the first one, would you get an infinite loop of programming? Sorta like inception.

Ok, Enough of this sillyness back to more important things.

Isn't there a programing challenge to make a program that can make itself as output?

edit, ah that would be a quine: https://en.wikipedia.org/wiki/Quine_(computing)
