The X server does not use .xxxx files in /home for display setup, it
uses /etc/X11/xorg.conf, which will be specific to the local hardware
(video card, number of monitors, etc.).

It is *presumed* that if you are in a shop with multiple
desktops/workstations using NFS / automounted /home, that the base O/S
on every machine is more or less the same version -- eg the admins do
'yum update' on all of the machines and thus keeping them all the same.

So long as:

If all of the machines are kept more or less in sync WRT system
software versions (which is good admin practice anyway), there should
not be any problems.  Some of your .xxxx files may have to test the
environment (eg X11/Gnome related ones should be checking this and/or
using relative placement geometries).
