two different KDE configs at once?

Sort of...  but maybe not for what you want.  kde4 installs into a whole
different configuration, so it's certainly possible.

That's not entirely true.  I've pretty much stopped using NX, but if you use
krfb to share your desktop (as you would for VNC), you can then have nx
connect using VNC - what's different about this from regular VNC is that
it's using NX over the network, then uses VNC only on the localhost.  I
experimented with it but can't remember exactly what it was I didn't like -
it might have been too slow, but it might just have been that it
constrained the size of my NX desktop too much (when I run NX standalone,
it uses as large a desktop as fits my client, when I share another desktop,
it has to use a desktop _larger_ than the shared desktop, so that
everything fits, otherwise you are always scrolling).  One of these days,
i'd like to see NX look like seamless windows in VirtualBox.

My particular complaint was kontact - because it won't let you start kontact
when it's running on another screen.  Briefly I had a working dcop script
that let me kill the other kontact, but then something was changed in
kontact that broke that.  But I can't see how it would help if I had a
different "profile" - then I still wouldn't be able to share the data in
the program.  I might as well have two separate users.
