I've already got a thread moving data around, and I know that when 
data's actively moving that the user isn't fiddling with keyboard or 
mouse (odds are he's got his hands on a MIDI device). I can also assume 
that he used the GUI shortly before data started arriving, so in 
practice I can use a 30 secs foreground timer (which already looks for 
and loads an updated backend .so) to fire an enable/disable command when 
the rate of flow changes.
