An interesting thread is developing on the decentralization mailing list on the issues of Decentralising Single Signon and how it relates to SXIP. Here's my latest post.

Agreed. But while lots of work is being done in the B2B area the only
people I'm aware of working at the weblog end, and with something
demonstrable is SXIP. The thing is Passport has failed, Liberty is aimed
at B2B. Which means there's a chance for a properly architected bottom

This is a pretty boring area ;-) but at the weblog end, comments spam is
a problem we all have *right now*. And the spammers and scammers are
getting more inventive and prepared to do work. It's not at all unusual

We're seeing each major blog platform introduce it's own centralised
authentication to try and deal with this. So in order to leave a comment
I have to have a Blogger, Typekey, Userland, etc etc account depending
