The thing is when I used internet cafes, the first thing I would always open would be email.

2 and 3 and really valid though.

It would be interesting if you could integrate a mail handler to this service so that you could simply email them to request a session.

The thing is I'd log into my email anyway to check for new messages.

I think the invites are better in this case. The author made a similar point of Google+. Essentially, by not letting anyone in right now, and only having invites. That means no one can come in now and see it as a barren wasteland.

When they send out the invites, they'll probably send it to all the people who registered at the same time (hopefully a lot by that time) and when they all join on at once, they all see each other online. No wasteland problem.

Seems like a good solution to me.
