Sure, Paul, I understand all that but this was going to be just a small
piece of a larger demo to a mixed group of new users and folks who more
work with Linux than use it for recreation, and if I could get
everything working in a representative way within the VM that is to be
the centerpiece of the presentation it would be my preference.

With the exception of two members, this group is not involved with and
probably not interested in music production. If anyone was interested
in details of functionality and actual performance, I'd schlep my SMP
workstation in and knock their socks off.
