If you can run Squid, you can multihome your web connections today.
It's a little bit awkward to configure, but then again, so is
Squid. People are welcome to poke at, fold, spindle, or mutilate:
http://nms.lcs.mit.edu/ron/ronweb/#code
(Part of my thesis work, Monet is a modification to Squid that causes
it to try to open N TCP connections to a Web server that it wants
to talk to. It uses the first SYN ACK to return, and closes the
other connections to be a nice neighbor. It's shockingly effective
at improving availability to Web sites that are themselves multihomed
or otherwise good. Warning: Often still leads to annoyance if you find
yourself able to browse the web but not do anything else. We do have
a NAT version of this that works with arbitrary protocols. If people
are interested, I'll try to convince my former student to dig up the
code and make it a bit prettier.)
