This is a great idea, Lawrence. I know I am much more likely to try this 
than I would be to replace my working BE with 0.28.

Is there any chance the 0.28 code could run a *slave* BE talking to a 
0.27 *master* BE? That's another scenario under which I could test. It 
would even allow me to temporarily reassign my tuners to the 0.28 slave 
and try recording.
