This works flawlessly with a cheap hardware running openbsd+pf.  I've
done this in several instances when load balancing "users" over two
connections was required.  I've attached a pf.conf that does just
this.

The other solution(if you want to call it that) was a Symantec
dual-wan router/vpn appliance which was horribly broken and met a
timely death once the openbsd box replaced it.
