So any network protocols above UDP/TCP should work as well, e.g., HTTP, FTP, SSH, DNS.There is an existing uIP which might cause confusion, not sure if you've seen it. First I thought you were using that :). http://en.wikipedia.org/wiki/UIP_(micro_IP)
Is the primary motivation here to allow unprivileged guests with networking without providing unprivileged access to raw networking or just to make networking Just Work?
We've explored various things in the past like using a fscap based helper to open tap devices which can help with the Just Works parts.
Usermode TCP/IP can be quite cumbersome for users as things like ping and ip6 won't work properly.
