Any Clients support Anonymous SASL Authentication?

Does anyone know of any XMPP clients that already support Anonymous SASL authentication? I’d like to be able to test some stuff with OpenFire, but I can’t seem to find a client that’ll do Anonymous…

I know the XIFF API supports it, and I know the XMPP4R ruby library does… but does anybody know of an example of an actual Jabber client that supports anonymous auth?
