And, unfortunately, scale to taking huge numbers of seconds for stuff that
isn't already cached. I just queried a bunch of sites and got times from .1s
to 8s for 3-lookup queries. While I'm willing to wait for 10 seconds for
a return, I'm not sure I'd be willing to wait 1.5 minutes. People have
this perception that the net should go fast (unfortunately even when they're
dialed up with 2400bd modems :-). This'll be a win for a.com, but a real
lose for CompuServe.com :-).
