KDE 4: trouble setting up two separate Xservers

I was, I think, dreaming about this problem as I slept, today.  When I 
woke up...

The thought occurred to me that plasma-desktop is but a single component 
of kde4.

I actually kill plasma-desktop from time to time here, because it's still 
lacking the panel fold-away buttons that kde3's kicker had, and while I 
normally have an always-on-top system monitor panel (running several
yasp-scripted plasmoids, from kdelook) across the top of my top monitor, 
and when I want to run something full-screen across both monitors
(full-screen mode doesn't work, that's only one monitor), it's easier to 
killall plasma-desktop to get rid of that always-on-top panel, then restart
plasma-desktop when I'm done, than it is to change the panel settings.

Thus, when I woke up today, the thought occurred to me that if it's only 
plasma-desktop that can't be run more than once, depending on the reason 
one wants to run more than one instance of kde4 and whether both instances 
actually have to have plasma-desktop running, it may well be possible to 
run two kde4 sessions, but just run plasma-desktop in one of them.

The other could use some other desktop or at least launcher, krunner, 
perhaps, if it's possible to run two of those each in separate sessions, 
or run plasmoid-viewer with a launcher plasmoid (kickoff, lancelot, kmenu-
classic, whatever), or perhaps plasma-overlay, which is designed to run as 
a screensaver, or just run a konsole window or something and launch stuff 
from it.  Or use a non-kde desktop of some sort.

The point being, still run with kwin and etc, so it's a kde session, just 
without plasma-desktop.

It may also be possible, I don't know, to run plasma-desktop in one 
xsession, and plasma-netbook in another.  I'm not sure if those two can be 
run concurrently or not.
