Why does the user need to receive a Yo? Wouldn't it be better to ask users for their handle, and then tell them to Yo a specific account in 30 seconds? If it worked like that, yoauth couldn't be used for spam, nor could you Yo someone you know in order to get their credentials if they replied.

A friend and I built a similar service (also at the Yo hackathon) and what you mention is similar to the way we handled it. I don't think it's been publicly announced, but Yo can now receive links on iOS.

The service we built (http://yosesame.com) works by having you Yo YOSESAME, which signs you up if you aren't already and responds with a URL that logs you in right way. The way Yoauth approached it is interesting, but you're right it's a bit strange to have to receive a Yo.
