I have an x-terminal (ncd) which is used by different groups for
different purposes.  Each group uses a different machine as host.
Unfortunately, users often leave minor programs (like a window manager,
say) running after they logout, thus making life difficult for subsequent
users who can't run their own wm. 

The obvious solution is xdm(1), but I am having a hard time seeing how the
XDMCP supports my needs.  What I want to do is run a sort of meta-xdm that
puts a screen on the xterminal advertising a collection of hosts
that would be happy to manage the display, then let the user select
the desired host.  At that point the standard indirect protocol would
work fine, except that only one host would be in the list of acceptable
hosts.  Unfortunately, I can't see any way to do this within the protocol.

Could someone explain what I'm missing, and (please!!) maybe even
point me in the direction of some code?  (I must be dreaming....)

TIA
