Best route for re-implementing TCPHA

TCPHA (http://dragon.linux-vs.org/~dragonfly/htm/tcpha.htm) provided
several neat features for content and health aware load balancing. I
am looking to re-implement on the 2.6 kernel and I am struck by
indecision on a few key features.

In particular the original project created its own polling methods for
TCP sockets based on fs/select.c and tcp_poll but to me this seems
inelegant. I am wondering if there is a "correct" way to poll sockets
in kernel or should I simply call sock_map_fd on the kernel socket.

After extensive searching I did find this post
http://permalink.gmane.org/gmane.linux.network/180354 to this mailing
list, but it does not seem to contain an answer as to the correct
direction for polling tcp sockets in kernel.
