And then, to save development time, we'd have to run linux (m68k version) 
on it.  Which TBT, I wouldn't be in favor of as making it compatible with 
the 6309 instruction set has not been done.  So I think it would be 
logical to actually port nitros9 to it.  Its much simpler and would 
probably run 20x faster than the linux port.

Of course then, we would start porting the ethernet drivers and the tcp 
stack so we could put it on-line.  Then we'd have our first exploit and a 
security model would be put forth & eventually coded.  And by the time we 
had it as secure as linux, it would be as slow as the m68k is on an 
amiga, and that's so painfull its soffocating.  Been there, done that.

Whatever you do, don't restrict its address buss as was done on the amiga 
mainboards.  For m68k linux, that's a peephole that can't be usefully 
worked around.
