Nice product. Making it easy to use/launch sounds like a big plus to me. I originally thought this had actual voice chat along with the visual element, but that's not the case, is it? Oh well - bummer.

One use case that could prove useful for me: I can see using this to help design UI on distributed teams - rather than creating or modifying screenshots and sending back and forth, you could mark up ideas at the same time.

In the demo, were you guys writing on a Wacom type of device or something? I can never write that nicely with a mouse or trackpad!
