I made another multihome pacth for ipfilter.
This makes it possible to load-balance up-stream
access-lines dynamically on the basis of RTT.

On a patched ipfilter router, TCP SYN packets
are duplicated and forwarded to a TCP server
through every access-line. The source address
is re-written to the out-going network interface's
When TCP SYN-ACKs returns, the ealiest one in
the TCP session is accepted as a normal SYN-ACK
and other late comers are dropped and instead
RST packets are sent to them.

Please refer to the page below for patches and
for further description.

I'd like to have any comments.
