One of the Mumble developers gave me compiled app for Mac OS X back in December 2007. It seems to work, but I haven't had an opportunity to use it in a game. I have browsed and connected to Mumble servers, though. In case anyone is interested, here is a link to the DMG file:

...So what is the official developer stance on integrated mumble with nexuiz in the future?

My stance is that it would be great to have but the current dev team is rather small and could need help in such huge tasks. Remember most of use are also working fulltime and some have family iirc..

i think i made a rough line out how this thing could be made in my post http://alientrap.org/forum/viewtopic.php?p=35048#35048 and if no-one decides to get on with it, i might try to learn how to do that kind of stuff. I suspect that wouldn't be easy, but i would give it a try to learn some programming language that you can make apps in. I suppose i wouldn't succed, or finish it in 3 years.
