This is becoming progressively less about netbsd and more about parallels, so 
we should really wrap this up. 

I don't know about a PPP interface, but you should be able to create two virtual network devices 
for a netbsd guest in parallels and bridge these  virtual nics each to a separate wired or wireless ethernet device in OSX. After that, you can make them route just they would with any 
other netbsd box. 

Parallels has a 30 day free trial. I'd suggest you get a copy and try it out as it seems pretty
likely that it will work, but it seems pretty unlikely that anyone will have exactly the same 
setup you have in mind.
