If you're the least bit interested about how integrated identity is going to pan out online - I suggest you head to the Internet Identity Workshop - B in Mountain View the first week of December. Most of the conversation is about making identity platforms work with each other (like OpenID, Higgens, CardSpace, SAML, Liberty Alliance, etc, etc), but there are lots of other fascinating topics. I'm specifically interested on how people use identities online (well, I know how people use identities online) but how the technology facilitates or makes it difficult for people to have single or multiple identities online.
Unlike the real world (meatspace) there is no corporeal body to anchor you online (unless you create one). This online anchor is most often a website,sometimes a blog, and rarely incorporates the various personalities one has. So I'm going to watch, learn and think about this online anchor for your (and mine) online identities.
Reviewing the technology, gives me lots of ideas for fleshing out, using and extending your/mine/my clients online brands. I believe we are at the tip of the iceberg on this. And of course, I expect to find methods of enlightenment and self-actualization buried in the technology.
