The attempt to merge various identity standards appears to be on the rocks with Johannes and Kaliya commenting here about the withdrawl by the Identity Commons folks.
Johannes is on the money about the culture clash. But in the end, the real loser is the customers as the the Identity version of HD-DVD vs Blu-Ray debate over competing standards and features will continue.
Customers, it is your time to shout! Contact your vendors (including my employer) and make yourselves heard! The vendors and open source communities need to hear from you!
