Looking For UT Ad Hoc On PSP - Or Multiplayer FPS

[acer5050]

Does anyone know of unreal tournament being played on a psp?

or if nothing else a look alike? that would run on the psp?
If you know a psp developer let me kno! I can get the source to a look alike opensource fps if they think they could port it.

EDIT

would it be possible to create a homebrew psp game that you could make maps on your pc then transfer them to ur psp and play them? Then in adhoc mode if another player does not have the map it sends it. kind of like how UT2K4 works.

Whoot, not exactly unreal but EXTREAMLY COOL
