FYI, 1000 players logged in is not possible because of the limitation in personal computers processor speeds. Unless they have 20 - 4ghz processors, they would freeze up.
OSI had a max of 2000 players on at one time for each server, average was about 500. That is with the world split into 8 different soloris computers.
But hey, it might be possible that he owns a SGI server and uses a 1gbit connection.
