Saurbraten ( http://sauerbraten.org/README.html http://sauerbraten.org/README.html ) is under the ZLIB license, and the engine tech is open source, but the content itself may require separate licensing (then again, it's pretty easy to hack on new textures and levels).
Nexuiz is under the GPL ( https://en.wikipedia.org/wiki/Nexuiz https://en.wikipedia.org/wiki/Nexuiz ), and more importantly, so is its content.
Basic game plan (to me) would be to fork the engine code for one of these and add hooks for servers events and reporting, pay some devs to build a few arenas, and then test the waters. You could probably have pilot up in the time it would take to finish wrangling legal with anyone else.
