FWIW, OpenBSD 3.2 with pf  (to be released on 1st Nov.) does this with ipv4, but
I haven't tested it with ipv6 yet.

See  pf.conf man page at
http://www.openbsd.org/cgi-bin/man.cgi?query=pf.conf&sektion=5&arch=i386&apropos=0&manpath=OpenBSD+Current

the section that will be most interesting for you is ROUTING. As mentioned I
haven't used it with ipv6 yet.
The route-to command is already present in 3.1 but I am unsure if this does
actually work with ipv6.
