The multi-user Cut The Crap client server, uses a connectionless, UDP protocol.
It means that there is no resource limit associated with thousands of clients connecting to a single server. That the limiting factor is the number and frequency of the requests made, rather than the number of distinct clients.
It means that the server could be shutdown and restarted without the clients needing to be restarted themselves.
It means that an option to provide http based connection is a possibility
in the short term.
