It has come up several times in the last few weeks.  I just haven't had time 
to look into it.

The driver just wants a file descriptor that it can read and write packets to. 
 It doesn't care how that descriptor is set up.

That is purely user-level code.  If you can write a little proggie to set up 
slirp and communicate via it, you can probably just drop that code into the 
driver.
