Whadya mean? There's still muttley's UT2003 Demo server...
edit: just tried playing there again, and I honestly think I would have a better chance with zero ping and a blindfold! Walk four steps toward weapon, stop. Wait as screen yanks me back to where I started, then oozes me toward where I was trying to go (hopefully). Correct aim, walk towards weapon, stop, wait. You got the Rocket Launcher! Wooo! Find out you died about five seconds ago when a bot found you stumbling around near the RL. Respawn. Repeat.
Guess it just wasn't meant to be...
