Noobie's answer above DOES work. Just follow his instructions and you'll be able to play with no cd. You ofcourse still need your unique serial key to be able to connect to all servers, but it seems that this combination also allows you to host cracked servers and allow people without a valid serial key to connect to those cracked servers. These 'cracked' servers usually have a hint in their name like 'FLT' or 'cracked' and they don't check your key. I looked at the number of those servers and it looks like a 1 in 20 ratio. If these people actually would buy the game they would be able to choose from 20x the number of servers, very important with the number of badly run servers out there. Ah well, it's their choice
