With X11, it is possible to create a X window inside another X window,
even if it doesn't belong to the same process.

Therefore, it would be possible to have emacs create an emacs frame
inside another program X window.

Unfortunately, the API to do that is not exported at the elisp level.  A
patch to emacs would be required, and of course, the hosting application
would have to be modified to invoke emacs for its text editing areas.

X11 is under-exploited.
