Yes, qemu does this by implementing NAT and the
TCP stack in userspace.  What always made me unhappy
about this solution is that we have a perfectly fine NAT and TCP
in kernel, we just lack APIs to make an unpriveledged
user make use of it the way we want.
I hope you can avoid this duplication.

Another question is whether you want to implement a dhcp server.
