It would be awesome to find a way to make this work, and yes, it does sound like it's more of a marketing issue than anything technical.
I like the OAUTH solution. It's a bit facebook-ey to stick the name/face to the user, but it's fair.
Personally (and I do mean personally) I'd love to see it able to create "private" rooms for staging servers (web development) and admin-panels so I can instruct employees from halfway across the globe. I realize that's quite niche though, and not much of a market, but there it is.
Re: "private" rooms, we are thinking about this, just need to figure out an elegant solution...!
