The Internet Identity Workshop is happening here in Mountain View in a week or two. Its a great opportunity to talk BitCoin with a VERY active group of developers who are building a key part of the future internet. I think BitCoin ought to be integrated with those services, at least in the sense that those services tend to hold identity info.
My first guess is the BitCoin Address should be part of the data, but that's probably too little and too easy. I guess that you guys have already thought about this.
Maybe integrate the public keys so the OpenAuth libs can sign coins?
I'd like to do a talk. Give me some feedback guys!
