In theory, but it probably needs some coding love. The libtheora encoder 
assumes it's doing batch encoding and the output delay varies wildly 
with the motion content. With a "realtime" mode it should be possible.

I don't have access to the hardware. Can you try running an encode 
with libtheora 1.0alpha7 and see how far we are from realtime?
