I think coming up with increasing examples, as you started in your presentation, of how OpenID can work for higher ed is a good idea and would help make the case. Anyone up for a wiki? One I threw out to the crowd (I think I might have pinched it from somewhere, but I can’t recall where now) is around the whole repository scenario – currently we have all of these institutional repositories srpinging up with thesis and other scholarly publishing, but no simple way for people to interact with them, leave comments or interlink them. Much like blog comments, this to me is a perfect scenario for the low barrier use of OpenIDs – it deals with the spam issue but otherwise leaves it pretty open for people to participate.

Other examples?
