I will look into that, thank you.   That looks like a promising solution.

 It isn't something that I want to try to tackle when I am working
remotely via a windows machine, etc, but rather will wait till I return
to the office.

On an other note, I had the inspiration to try to remote desktop into a
Centos 6 machine that i have on my LAN, and that too failed for the same
reason ???  which makes me wonder about the xfreerdp setup on this Arch
machine.  I think I will bring the work machine home and try that as an
experiment.
