From what I read about Java NIO and non-blocking [Server]SocketChannels, it should be possible to write a TCP server that sustains several connections using only one thread - I'd make a Selector that waits for all relevant channels in the server's loop.

Is that right, or am I missing some important detail? What problems can I encounter?

(Background: The TCP communication would be for a small multiplayer game, so max. 10-20 simultaneous connections. Messages will be sent about every few seconds.)
