I'm sitting in the Ames Courtroom at Harvard Law School right now waiting for day two of the Berkman identity Mashup to begin. I missed yesterday because I wasn't willing to fly out on Father's Day. My panel in identity brokers will be at 9am.

As I got here and opened up my laptop, I signed into the Harvard wi-fi network. They allow temporary guest logins; you have to provide an email and telephone number. I don't know what keeps people from just giving them dummy data. Probably nothing. I was thinking, however, that you could use a reputation system to determine whether you wanted to give someone access. Reputation systems could have already verified email addresses and even phone numbers.
