Win 8 touch events in uGUI

I'm restricted to using windows 8 for my unity gui applications. There are known issues with multi touch support on windows 8 devices. Using NGUI I was able to create a solution where I have a window handle for my unity build and direct the touch events that I get to NGUI, so that the NGUI UICamera behaves as if it would get the multi touch events correctly. Now, I would like to shift to uGUI asap, but I wouldn't know how to delegate the touch events to my uGUI components. Are you still working on the Windows 8 problem, or is there a way to use my hack solution with uGUI?

Thanks in advance!
