Actually there's a different path of getting software composite managers 
to run pretty efficiently and we're researching it right now. Basically 
the problem we go back to is that framebuffer reads are killing us on 
every step of the way. So the simplest way of having Composite actually 
usable, that is already implemented in most drivers for other things is 
1) simply exposing hooks to fetch the data from the video card using 
full agp bandwidth,
2) using maximal sized transfers.
I have 2 finished for a8r8g8b8 visuals (but from what i've seen 
composite mangers deal with them) and I'm working on 1. So this stuff 
is really not hard, it takes little effort to get it working fine and 
most importantly working now. 
All in all, I think you worry a little bit too much. Just enjoy what 
you're doing, especially that you are doing great work and like I said 
I'll definitely help you once I'm done with a few other things. Even if 
we finished Xegl tomorrow it's still going to take lots of time before 
distributions catch up. 
And in the mean time since a few people expressed interest in Xegl but 
general lack of information about it seems to blocking them maybe it 
would make sense to create xgl-devel list or maybe even reusing xorg 
list for coordinating the development.
