Sounds nice, too bad there are no screenshots so I can't see what does it look like without giving my e-mail.

Does it run on an open protocol? (Maybe HTTP or XMPP based?)

That is right, I "exchange" screenshots against feedback, on a live interaction...

Yes, it runs on XMPP and SIP and WebRTC, and obviously HTTPS (because what does not?).
