Have you seen how User Mode Linux handles this?  IIRC you can run a 
userspace kernel, and have it talk to a networking daemon which runs as 
root.  Obviously this gives you a lot more fine-grained control over 
what the UML kernel actually sees - great for honeypots, because from 
"outside" it looks just like an ordinary running Linux kernel.
