In his recent post, Dan Farber relays a meeting of the minds over federated security issues that need to be addressed to move Web services and SOA forward.  It's interesting to see Liberty Alliance and Microsoft, if not on the same page, at least reading the same book.  And, in general, everyone agreeing that the security standards development process needs to remain as open as possible, but move a little faster, and become more interoperable.
