yes - me too, that's the first step .. xbmc seems promising, the way I've done 
it very successfully in the past is just sending frame numbers to pix-video in 
gem, using the computer that was running audio as the master clock. My friend 
found that just using omxplayer kept quite good sync over 20 minutes or so, and 
she is quite picky about that kind of thing. I didn't see the result myself, it 
was on the other side of the world.

After sync I want to tackle crossfades, which pdp might be able to achieve, then 
the kind of framing that can be done by moving a rectangle around in 3D, which 
will require some extra work. But not in a huge hurry, and a lot of other things 
to do, but should get my hands on a Pi in the next few weeks.

I've got lots of existing GEM stuff I was running a few years ago using a mac 
mini per projector that I'd like to port to Pis.
