Announcing YADIS...again

I'm going to "third" the comment.

After reading the docs, the goals page makes my BS meter tingle.

"to contribute a multi-vendor, multi-technology personal identity foundation
for Web 2.0."
"to follow an open, meritocratic process for doing so, e.g. by following common
open source development practices."
"to allow and foster innovation and competition within the personal digital
identity market."

Sure, quotes like this may sound like good and warm, but it's still fuzzy.

My Question: What are the *real* problems it's going to solve, and how are any
of these goals going to solve them?

"to further broaden the applicability and feature set of OpenID, LID, and of
other personal digital identity technologies"

Is it just a case of Profile exchange as Kurt asks? If so, I too agree with
What about things such as VCards? exposes many profile items on
their user's openid page. I can see some sort of standardization for profile
exposure (hopefully a light weight method) for computer system accessibility.
