[wp-edu] Federated Authentication? Anyone thought about it?

There is a Google Apps integration plugin that creates accounts on the
fly using the email address as a username. Can't remember which plugin
it was now.

Perhaps it's worth having a search, and/or posting to wp-hackers to
ask which filter would allow those characters in usernames.
