[mythtv-users] Multiple Screen Support?

[Brandon Sherman]

I'm eyeing an old Macintosh 512K as the box for my MythTV computer.   
I would want to replace the internal CRT display with a touchscreen.   
This way, MythTV's control functions are always visible but the video  
can be sent to the main TV for games, DVDs, TV, etc.

I hope that makes sense-- a control screen and a display screen, if  
you want a very simplified view of it.
Does such functionality exist in MythTV?

Thanks,
Brandon
