I was only able to host when entering my IP manually as static IP. There was still visible lag although we both came from germany.

I found the camera to be restrained to much, as Damocles (?) said. Try the UT2004 method, at least for the fighting oriented modes!

The menus are a bit to cramped, especially those in online mode. And you definitely need bots in online race modes!

Looking forward for bugfixes etc!
