Take a look at http://line.sf.net and 
http://www.ugcs.caltech.edu/~steven/lxrun/
I already begun porting LxRun, but there is a major problem, which the 
BeWine folk face also, which is that the virtual space in BeOS is 
reverse than those of Linux and windows (kernel from 0 to 0x7ffffff)
This will make things very tricky.

That's how LxRun works, it intercepts Linux syscalls (int 0x80),
which segault in BeOS and other Unices (BeOS uses int 3 for syscalls),
and reroute them.
