Yes, clearly.  Since this, unlike the EPG, needs to trigger action on the
set top, it might be better to run it in a fashion similar to what I
suggested for the frontend menu.

Oh, you're running two X servers on one system?  I assumed you were using
one system as a control terminal and the other for display.

I don't know about Qt (does that portion even use Qt?), but as far as the
X11 API is concerned, there is no reason why the same process cannot
communicate with both displays simultaneously, in which case there is no
need to move it into another process.

And again, there's no need to involve the network if you're only using one
system.
