I'm very impressed.
I had to reduce the resolution to 16 bits per pixel, but other than that the game looked great. I loved the weapons, they're both beautiful and functional, though I had trouble hitting anything in multiplayer because of the lag. ^_^
I really like the look of this game. Tell your mappers, modelers and graphics artists that they did a fine job!
I am impressed by the number of servers, although several disconnected shortly after I joined -- which leads me to believe people don't like me. (j/k) While lag has always been the bane of my existance (I haven't learned to handle it well), it wasn't unplayable. I'd love to give this thing a go on a lan server... and I'll bet I could do that with lots of friends at the college (we occasionally hold gaming nights).
I'd love to do a few mods of this game. It would be cool to make a Team Fortress Nexuiz, a few weapons mods... I even saw someone on a server say "I'd really like to see a realism mod for this game". Found that one amusing -- isn't one of the goals of Nexuiz to kind of pull away from the realism games?

Well, I imagine it wouldn't be too hard at all to jump into modding it, since it's based off of Quake1.
...though so very much has changed!
I had fun! All in all this is a very well-done game, and I'm quite impressed that you not only did this as an open source game, but also managed it completely over the internet, instead of working in the same building. Bravo, guys!
I'll have to share this with my friends
(excuse me while I fantasize about having friends... ooh that'd be nice...) ;D
and get some lan parties going to celebrate.
And this is going to be a hit at QExpo, too!
