No experience doing this with FreeBSD, but in general load balancing
situations, the short answer is that you can do a lot at your own end
and therefore control OUTGOING traffic (traf headed away from you) with
no problem. The bigger issue is getting stuff load balanced from the
other end - the other end is where you usually want share the load (ADSL
is all about downloading isn't it), you can't do that without the help
of the ISP. If you can't get help from your ISP, there probably isn't
much point in persuing this too much further; at best you'll be able to
do some very coarse LB. You said DSL not ADSL, so load balancing from
your end might be good enough (eg round robin webserving etc).
