Touchscreen/Multi-touch support

I was wondering if anyone integrated touchscreen/multi-touch input support to Torque 3D (or older versions). From the looks of it there are specific API calls in windows 7 you can use in a native app or you can use API's given specifically for a device which would work on multiple platforms so long as the device (hardware was the same).

I was wondering if anyone has messed around with this or has any tips/info to provide about how to get started. Or possibly even some code changes I could use.

We have been developing a serious game using Torque 3D for a while and currently have only really used and supported Windows so using windows specific API's isn't a big deal. It's a custom app/game for a specific client so it isn't something that will be on store shelves.

I am going to start doing research on it today, so this post is before any research. Figured I would ask just in case someone already wrote some code or had some info and was willing to share.

PS: Any info on where input is first handled would probably be helpful as well since it will probably all be done in the same place as mouse/keyboard input for windows is currently.
