As Simon Waters pointed out, there are lots of ways to do this that don't
involve DNS at all.
If for some reason you *have* to use DNS, however, and you control all of the
nameservers in this equation, you could probably create a generic name for the
fw/proxies and use a sortlist to sort the address list differently for each
group of clients.
