XInput 2.1 / multitouch branches

[Blub]

Hey there.
I've been playing around with the multitouch branches of xorg-git the 
last few days.

I'm about to build a multitouch table and currently am using my android 
phone to test the software. (With a little tool reading from the event 
device, converting its type-A multitouch events into type-B multitouch 
events and sending them over the network into uinput.)

I was wondering if maybe someone could point me into some direction 
regarding testing xi2.1. (applications/WMs or branches thereof which 
have some experimental support...?)

Currently thought about writing a "helper" application, which should 
basically grab the MT device to provide some control over windows 
(moving, resizing), but the grab seems to only deliver button events, no 
touch events (yet?)? (I'm trying to read into the xorg code so maybe I 
can provide a patch if it's desired, but I'm not yet familiar enough 
with it to make any promises :) )

Best regards,
Wolfgang
