that could be a solution, but this will tracking down bugs a difficult and long 
task, because you'll have to transfer the whole thing whenever you change 
something try to fix a bug

no available distro's: seems impossible to me
they all suck: this happens all the time :-)

i don't know anything about embedded systems

indeed, and that's IMO the main use of crosscompiling
the point i want to raise is that people who crosscompile for an i386/i486 will 
(most of the time) do this on a i686 host
people who crosscopile for an old apple or so wil do this (most of the time) on 
a new apple host
Am I right about this?
