As Identity systems become more popular across the internet there will be increasing benefits from binding a user's personal information to their digital identity. The ability to exchange these attributes between multiple services makes it easier to maintain a consistent identity across the internet. For example, if you move house, it would be great to be able to update your address in one place, and have that propagate to all Service Providers that need your address.

What federated identity attribute exchange services are available?
