Ping Metasystem Paper

I wonder if the timing of this metaystem paper from Ping is coincidental to yesterday's Cardspace /OpenID announcement?

The second integration scenario described in the paper could have come direct from yesterday's PR (albeit with an interesting SAML twist)

1. signon.com has implemented phishing resistant authentication and supports Self-asserted Card Space authentication. Alice uses her CardSpace Identity Selector to authenticate to signon.com.
2. After successfully authenticating Alice, signon.com use the OpenID protocol to redirect Alice back to isp.com

Or is this related to Kim's last-paragraph teaser from yesterday.

Really great news coming on Ping Identity.
