If you look at the docs for the Signed Claims[1] perhaps the most interesting part of this is the safe way to share content. Being able to cryptographically verify a claim of access to or ownership to content sounds pretty awesome to me.

I spoke to Brad and Brett at OrdCamp[2] here in chicago this weekend and it sounded pretty interesting. They plan to make the tooling around this hide the difficulties in dealing with public private keys from the average user. I suppose if it's done right this could do for sharing content what SSL did for Commerce on the web.
