You're talking about bonding DSL lines, which (IIRC) has been discussed
before once or twice. Check the archives for "load balancing" "rate limiting"
and "bonding" ...

stop right there. :) Having your ingress traffic come in on a different path
than the egress traffic took on the way out is asymmetric routing, and that
pretty much _requires_ some kind of routing to be going on (BGP most
generally). The source address of outgoing IP packets will be used by the
destination machines in order to send the replies. Think about it for a few
minutes.

altqd(8) can rate limit; but to specify different routes based on source IP
(which is, I think, the best you can do in this situation), you need to
investigate some of the options in pf.conf(5). Basically, I'd divide up your
internal machines into groups, and setup your pf.conf such that packets from
group A get routed through interface 1 with gateway X, packets from group B
get routed through interface 2 with gateway Y, etc.

You may as well use all 3 for outgoing; there's no way you can do asymmetric
routing unless you are, well, ROUTING. :) That means BGP or some other
routing protocol, which means considerable setup on the part of your ISP.

CC'ing the list for the sake of archives (and hopefully discussion by those
who have dealt with this problem before).
