I suspect Linux based systems are a few sigma away from the original goal of a cheap pic choice...:)
But to get back to the original point, you can get samples of most of the PIC chips from MicroChip for free. I think the limit is 3 per week. Or 30 days, I don't remember.

Can you pack it into a big M4 - sure, it'll be a tight fit and you may not have everything you really wanted to have. Oddly enough some of the M4's have better native ethernet than some of their "big brothers". Weird….
