Regarding implementation of multi-touch in linux mobile operating system

Hello all,

      I am an undergraduate student.I am trying to implement multi-touch

in linux mobile operating system under my final year undergraduate project.I
am planning to use QEMU emulator for this due to the high cost involved in
using mobile hardware.Thus I want to ask if anybody has implemented or is
implementing this under QEMU emulator which uses interface of libSDL to
interact with host X server.If so then please suggest something in this
regard.

Thanks,
Amey.
