SRS touch support?

Hi everyone,

So we've rolled out one SRS (SP4+SmartDock) as a test with success. Currently, it's hooked up to a projector. We're looking at replacing the projector with two TVs since v3 supports it, but I was curious if SRS supported touch panels. I can't find any documentation or mention of it. Can anyone enlighten me? 

Is touch/whiteboarding limited to Surface Hubs, Crestron, and Smart Room solutions?
