"new login in nested window" doesn't play nice with xinerama

On my multihead/xinerama system, I find that the xnest integration isn't very
usable. The resulting Xnest server spans part of both monitors. It would be
fantastic if the Xnest was the size of *one* of my displays.

Some thoughts and suggestions:

Solution #1: Probe for xinerama and create an xnest for a single display.

This has problems when some of the displays are a different size than the
others. Maybe you could choose the smallest of the set.

Solution #2: Make the window resizable.

I suspect this is *very* difficult. Unless Xnest is able to resize on the fly
(seems to be fixed).

Solution #3: Provide a way to pick a resolution.

Not especially user friendly, but it is probably the easiest solution and would
work for pretty much any layout.

None of these ideas are perfect. Any suggestions? I suppose what I really want
is an easy way to spawn a new session for quick user switching (I run my p2p
clients under reduced privileges in another account)

Thanks,

Adam
