Just a thought, but perhaps you could hack together a proxy.pac (proxy.pac
is a java script you know) that could take care of the NTLM stuff on the
workstation side. It'd be a pretty lengthy proxy.pac, but you might be
able to get the functionality you need that way.

Not that I've ever tried this, mind you :-) I'm just a big fan of the
proxy.pac system after I discovered many years ago that it relieved me of
a LOT of trouble in terms of browser configs.
