I haven't seen that class, I'll take a look. I didn't want to go through fred again because I don't see the benefit. I'm not trying to do any authentication (that part's already done), admins don't know the relevant password, so it'd pretty much be IRealm.requestAvatar. I don't understand why portal, credentials checkers... come into play. >> I don't see an obvious way to get a reference to the boxReceiver/boxSender >> from the responder method using documented APIs.
