As for the license things... Which commands/mods are we talking about?
Most of the modules are under the BSS license (which I'm pretty sure skidracer won't mind me posting):
Those that are derived from other sources (i.e. Ogg support, libpng, etc) each have their own licenses which you are subject to if you choose to use them.
