Just think, there are people out there "throwing away" an oc-3 worth of
bandwidth to IP over ATM overhead. Must be nice to live in a world of
capitalization where one could do such a thing. We use ATM for two
reasons, 1) it's still significantly cheaper than long-haul circuits of the
same capacity, 2) it provides some interesting abilites that are only
now beginning to show up in the mainstream IP hardware.
