The new master is in /master_django. It's written, as the name indicates, using Django, and includes a script to run it on CherryPy, which makes deployment very easy (the Django dev server isn't suitable for production, which is why something like CherryPy is needed; of course, you can also use Apache/lighttpd/etc., but that requires some setting up).
The goals with the new master server are
- Clean extensible codebase: Beyond the basic functionality, additional features will be implemented as plugins
- Federation: Allow anyone to easily customize and run their own Intensity Engine master server
- The Intensity Engine 1.0 release depends on the existence of a few good maps/games
- The public launch of Syntensity depends on the Intensity Engine 1.0 release and on completion of the new master server
