Newbie question -

[Thomas Chadwick]

The problem with what you describe is that you can have 1 and only 1 window 
manager per X display at a time.  In other words, you can't connect through 
XDMCP, which launches a window manager, and then launch a local window 
manager on the same display.

I don't see what would be wrong with running 2 instances of XWin.  You could 
start the first one with DISPLAY=:0, and do the XDMCP query and all that.  
The second instance of XWin could be on DISPLAY=:1 and launch a local window 
manager.  The only thing that would give away the fact that they are not the 
same DISPLAY would be the fact that they would apear to occupy different 
"planes" in the "z-axis".

You should be able to make this relatively seemless in your "startxwin" 
script.

Come to think of it, an alternative to launching a second XWin instance 
would be to use the Windows Start button to launch local X apps.  As I've 
seen mentioned here before, you should be able to write a simple 
"startxapp.bat" script which sets the path, DISPLAY, etc. and then runs an x 
app that can be passed in as a command-line argument.  You could then create 
a group off the Start button with a different shortcut for each X app you 
want to be able to launch.

The drawback to this would be that you'll get a separate icon for each local 
X app launched in this manner which, when un-minimized, is nothing but an 
empty box.
