i haven't skimmed the patch, but i believe the "standard" solution to
this problem is to tell simh to use a second ethernet adapter in the
host machine.  i can certainly ping (or mount nfs volumes from) my
laptop from the simulator running on my laptop if i have two nics in
it.

i haven't tried compiling anything yet, but now that you've pushed me
this far, i'll have to.  :)
