Sounds like the LVS project's TCP splicing code is what you're after:

http://www.linuxvirtualserver.org/software/tcpsp/index.html

This allows you to connect ('splice') two sockets together in userspace, so 
the subsequent forwarding is handled within the kernel. I've never used it 
myself though.
