Nope. (Though, none of the other OS X Chat program's we've looked at have
this problem. So, you could run Adium or Proteus over Tor, for instance.)

Please let me know if you can get it to work. :)

Wouldn't this be equivalent to changing the login server in iChat's
preferences to "localhost"?

Yep. We thought of this, too, but writing an an application proxy for AIM

I know of, and it is subject to change without warning.)

Oh, kinky. I'm not too keen on that method, either. (Sigh. An iChat plugin
API would be *so* useful.)
