Hi,
I see you're busy discussing other stuff and my message went unnoticed :) I made a look to existing network branches, found many of them. LWIP is interesting. Alexey said the best way is to join your irc channel. I will try to occasionally join, but in your project, mailing list must be a primary point of discussion not irc channel.
I think I start from making a simple, but robust tcpip driver (with help of numerously available source code of tcp/ip protocol implementations). Hopefully you could give me branch access, it's gonna be hard to develop it with patches.

P.S. I really like your "kernel coding style", quite rare to see that in opensource projects. Most of foss projects utilize linux-alike stlye, whic is harder to read and not that clean.
