sum up your pitch to make it easier for users to get what you are pitching.

"collaborative zoomable user interface to create sketches" is the same as "multiuser whiteboard" just easier to get.

As I believe the zoom makes it more unique, "multi-user whiteboard offering unlimited zooming", or the likes. But you're absolutely right.
