I was under the impression we'd prevented that by use of a random salt
chosen on-the-fly for each login attempt ... have to go reread the
thread to be sure though.

In any case, if your threat model is a dictionary attack, what's to
stop the attacker from using a dictionary of likely usernames as well?
I still don't see much security gain from hashing the username.
