Instant chats and central servers

Sean,

  There's a bunch of machines for AIM, spread out across the
AOLosphere... there is no one server that will take down the service.
(That's for the Oscar stuff; the TOC stuff, which the open messengers
use, is also clustered in the back end, but there is that One Server
You Must Talk To(tm).)

  I imagine the other services are similar.
