Comment 2 for bug 318164

It's trickier than that. The services_account module lets you change your nick, but still be identified with the old one. Thus, we need to handle differences between nick and account sanely. How do other services deal with this?

I think if we can properly handle the accountname stuff, +r becomes a special case we can deal with in the protocol layer (or maybe an intermediate layer between protocol and controller?) by restricting accounts to the nicks they match.
