If you get to the position of having more than a few hundred players
online, you'll want to be thinking very seriously about distributed
servers, most machines couldn't cope with that sort of overhead (granted,
some very pumped SMP/ram-by-the-excavation-load superbeasts can), and/or
setting a cap limit on the maximum your machine seems to cope with
(obtained through trial and error), with some sort of login-time limit for
existing players (think BBS).
Even not using a thread for each player, you'll still be processing a vast
amount of information, and doing vast amounts of work, which would floor
you anyway. :)
