I am not an expert in Twisted, but from my understanding, the "string"
requirement is there to provide a plugable interface. So that you can
have generic credentials checkers, working with generic realms.
Having simple "strings" could also help with AvatarId serialization,
in case you have the CredentialsChecker on one computer and the you
will pass them over network/socket to a remote Realm.
I have also asked over IRC and I got the good to go answer for using
anything as AvatarID.
As long as you are only using your custom credentials checkers and
your custom realm, everything should be ok.
I am using Objects as AvatarID without any problems.
