We're actually playing with Oracle apps - I'm told they already run on threaded mode on NT ... I personally get the feeling that Oracle's commitment to Linux is distinctly half-hearted. The whole support matrix debacle was pretty indicative, IMHO. All personal opinion, I speaketh not for IBM.

We can but try, but I still think some transparent magic would be implementable.
