I'd be curious to hear how your IP-MAC mapping works. Is it some sort of stochastic token passing between neighbors? To what size networks can it scale? Some obscure questions, since you've seriously worked with the metricom hardware: how intrinsically doppler tolerant is the communications waveform? What modulation scheme? What chip rate?
