I'm not shure if this setup would ever be "stable".
also with ucarp tweaks.
hopefully freebsd supports soon more than 1 route.

I'm not shure how I have configured that (~6months ago).
Now with ucarp I use a /32 for the interfaces as ip and
the virtual ip is added as an alias.

As far I remember, freebsd changed the multicast-interface to 
linux-style. Source code seems to be already there, only makefile needs to 
be changed, to support freebsd <7 and 7.
