Running A Generic Application In an X Window

[Dolloff, Matthew D. (JSC-ER7)]

That looks like it might do what I want actually.  The only catch is when I try to run Xnest with -parent I get the following error

[mdolloff at dolloff-matthew ~]$ Xnest :1 -parent 48234555
Could not init font path element /usr/X11R6/lib/X11/fonts/TTF/, removing from list!
Could not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing from list!
X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Serial number of failed request:  99
  Current serial number in output stream:  100


Any idea what is going on?  Sorry for all the questions, but I am really new to X programming.

Alternatively, you could run Xnest in your application-supplied window
using the -parent switch, then run the application on the Xnest
display.

As the application would be running on a separate display,
inter-program communication (copy/paste, drag/drop etc) won't work
without some additional effort.
