Now that the Guild Wars demo is long over I'm playing UT2004 quite regularly again and I'd be interested in our own server, though I am currently jobless and wouldn't really be able to help fund one. There's also the problem of where to locate it since we have members all over the place, and getting good pings for everyone is probably not an option.
So, in theory I'm all for it, but in practicality its feasibility is questionable.
