I'm trying to figure out the audience. I've never had to collaborate on a mockup. I make mockups. I review mockups. I mark mockups up. But I've never wanted to do one live with someone else. That's just me though so an example of when this is used would be great. Some feedback: I use Balsamiq and have for years.

I have a real need for such a tool - I work at a non-profit (MAYDAY PAC) and we pull expertise from distributed technical volunteers. While it's a good start, I agree it's far from "We fixed mockups" To your point: The inability to use pre-drawn UI items here is a deal breaker.
It remains flexible enough to play with visual concepts outside the restrictions of a UI kit. That's a good thing in my book.
