This is possibly a stupid and naive question, but I'll ask anyway ;)

I like the idea of MPX and have followed it from afar for a while (i.e. 
I knew what it was and had a peak at some videos a while back!).

Your above comment immediately makes me think of laptops with 
mouse+trackpad. These would presumably count as multiple input devices, 
so I wonder how the behaviour is selected. Do you have to explicitly 
configure them as independent pointers or can you configure them (as 
happens now) to control a single pointer. What is the default? I'd 
suggest the default should be the status quo (e.g. you have one pointer 
unless you specifically ask for more) so as not to confuse a lot of 
laptop users out there.

Perhaps this is a non issue for other reasons?

Anyway, well done with the work. It's been a long time coming. As I said 
recently, there's always something nice to look forward to in xorg these 
days.... I like xrandr 1.2 then the intel modesetting and now there is 
kernel based modesetting and dri2 stuff to look forward too as well. Ace!
