Oh, yes I know. It's the same mechanism that allows LTSP to work.
It would be a good idea.

Yes, you are right! My fault during typing.

Yes you have to stop xdm and start again. Anyway that trick could be used to
have higher resolution than 1024x768, performing the following command
on the dom0
for instance: Xephyr -ac :1 -screen 1280x1024
and the domU's KDE should keep all the available screen space, autoresizing the
screen (resolution).

Yes, it actually uses a Xorg nested server (BTW: Xephyr is the
evolution of the old
Xnest) so, no problem with the mouse and keyboard.
