Seems out of scope to OP, but cool info nonetheless. I'd like to get my web team to ditch a couple ISA servers for this, but sadly I doubt they will...

This might be worth looking into as well!
It's an open source load balancer that was originally developed by
yahoo and released into the open source community. It is now a part of
the Apache project:

Ci$co calls this Policy Based Routing. I'm not sure if FBSD or another package such as pf allows similar functionality. My guess would be yes - but I don't know anything about that.

In the lab you could MAYBE get a stable/usable connection from multiple providers (with just ppp or 'x' encap) by splitting the requests on the egress side - but it's highly unlikely in the real world. In most cases the traffic load is asymmetrical and heavily biased towards ingress traffic, so even if you could get it to "work" - it wouldn't provide much benefit.
