Before I head out to purchase a multi-touch display, I am curious what the limitations are of the standard pd interface.

If I create a patch that simply has two v-sliders, would I be able to manipulate both simultaneously on a multi-touch display?

If not, would it most likely be a limitation of the OS, pd, or both?

thx

the answer is no, and the limitation can be both OS and application.

The answer is never no. A lot of multitouch projects use TUIO, which is a messaging system that can be routed over OSC. Therefore, you can interface them to Pd. You won't have the same interactivity as a mouse though, but then why would you want multitouch to emulate a mouse.
