A few weeks ago, I emailed Johannes Ernst, asking him how (if at all) he saw lightweight URL-based ID management technologies like LID being used to express group membership semantics. As he promised, he’s put together a long post on group implementation in LID, which answers my questions.

On the plus side, I’m encouraged to see that this type of use case has been on the minds of the ID management players for at least a year, and that they recognize at least as clearly as I do how powerful this concept could be. However, it’s not implemented yet, which means I don’t get to play with it. Too bad; the possibilities for (creative) destruction boggle the mind.
