Although, considering what can be done with the Contiki browser on a 1MHz 8 bit 6502 or Z80 with 64kb of RAM, porting it to an 8MHz 32 bit 68000 with 128k doesn't sound like a bad idea at all.

Can anyone here even give a feasibility estimate for such a project? Porting to System 6 would be ideal; perhaps the whole Contiki OS could be ported to run as a Mac process. It is designed to be highly portable.
