I was babbling on about some problems and somehow got cut off by my 
mailer:

Note that two invocations of route(8) failed about mid-way through.  I 
can't figure out why, but manually typing the route commands after 
boot-up seemed to go just fine (no error messages, and routes installed 
correctly):

route add -inet6 fe80:: fe80:;1%lo0 -prefixlen 10 -interface -cloning
route add -inet6 ff02:: fe80::1%lo0 -prefixlen 16 -interface -cloning

As far as your plan for determining the default scoped interface route, 
it sounds good to this newbie.  One nitpick might be to move the 
ipv6_default_interface line in /etc/defaults/rc.conf so that it is next 
to the other definitions that begin with ipv6_*.

Thanks!

Bruce.
