Thanks for your follow up. My low level knowledge of X and GTK is
lacking, so my perspective may seem overly simplistic. As per Brian's
response last evening, it became evident that it was more involved than
I had anticipated.

As per your comments on freedesktop.org, perhaps this will come in time.
There are occasions when I find that this would be nice to have, but as
always, there are trade-offs. For the time being, I much prefer the
overall operational characteristics (and performance) of non-xinerama

Thanks again,
