This is really good news for all SAML fans: Sun released a non-assertion covenant (NAC) for SAML v2, similar to the one that covers the Open Document Format since last year. This means that the last (and as far as I know) only hurdle for vendors (like e.g. Microsoft) to implement SAML v2 is gone. It will be really interesting to see when and - more importantly - who will pick up on this offer.
