  Yes, I know that.  However, last I looked, one could not have 2 different X-servers using the same video card/resources.  If I have a single X-server running the local linux display (normal interactive stuff) and another running a remote TV, I then run into issues of window focus for the FE and directing input into it.

  I also run the FE in a script, such that if it (or the X-server) dies, it restarts everything.  While things are pretty stable, it occasionally does happen that something crashes, and being able to only restart the myth portion with affecting my interactive session is nice.

  I maybe should re-examine this - at one point this was also driven in that the FE was connected to 2 different TVs via a splitter, which had different properties.  So I had set up a hot key on my remote that would cause mythtv to run a script, switch the resolution of the X-server to what the TV supports (either 720p or 1080p), change the profile that mythtv would run as (different audio capabilities) and restart the FE.  I don't have that issue anymore.
