"Electronic Arts licensed Ritual Entertainment's Heavy Metal: F.A.K.K.² engine, which is in turn a modified Quake III Arena engine. The most notable changes in the engine include the use of the Tiki model system, which enables the engine to use skeletal animation among other things, the Babble dialog system which enables lip synching of audio with character animations, dynamic music system, scriptable camera, particle system and extended shader support.[4] The changes implemented to the engine for Alice remained minimal however. The game's .bsp files even retain F.A.K.K.²'s headers, albeit sporting a different version number."

I think the work is already 95% done, just needs a little tweaking to get Alice running on an N900 by using ioquake3. If it didn't use the Quake 3 engine I wouldn't bother bringing it up. Oliver McFadden expressed some interest but I guess he isn't working on ioquake3 anymore.
