Moving that change from libXinerama into the Xserver code is actually  
a good idea. Maybe that is also possible for all the other changes in  

Also, I would like to get rid of that xinerama.conf and turn it into  
some sort of FIFO socket.

There is no such list. We coordinate via IRC (#arctica on Freenode).  
The current phase is clean-up-clean-up-clean-up. The other current  
phase is replace libNX_X<*> by libX<*> where possible.

If you are available for coding, maybe you feel like working on the  
Xinerama change?
