I don't think this would be possible.  The network control message only
terminates when a value is returned (in this case button number etc.), so
there would need to be some way of telling the dialog to respond to
actions other than keypresses.  A good idea but I think probably beyond
the first implementation!
One thing that did occur to me is that there should be a configurable
timeout.

Nope :(  At least I don't think so, because mythfrontend will need to be
visible. The other option would be to just create a separate application
to display dialogs, but I'm not sure how well this would work since it
would need to create an instance of mythcontext, set up lirc etc and then
return focus to mythtv.

Again, no.  Not sure I'd want it to work like this, but you could always
send a pause message via the network control before invoking the dialog.
