Cool thing! We might want to place the fuzzing tests in the 'test' directory of the main rep, so they can be used on other platforms, too, just like the unit tests... if that works with afl?

Do you mean the input packets? They have the same hardcoded MAC and IP addresses as the fuzz.c test program, so they are pretty tied to the unix/fuzz application. There is nothing platform-dependant in the code though (more than C stdlib), so maybe all of it can be moved somewhere. I don't know what other advanced fuzzers there are for other platforms though, I think everyone just uses afl.
