Each host (backend) has one recordings directory.  Therefore, the master 
and slave can use different directory structures.  Each recording 
specifies the hostname on which the file was recorded, so in the event 
that the file is not in the local storage for the frontend, the backend 
that recorded the show will be asked to stream it.

Sounds right, but I've never tried this.  Probably actually slightly 
more complex depending on which system is requesting it--if there's a 
frontend on the master backend, it should be able to find it in the 
local storage, so it should be able to play it.  But a frontend on any 
machine other than the one with the local copy couldn't play it because 
it doesn't exist where it's supposed to.  However, a simple "UPDATE 
recorded SET hostname = 'masterbackend' WHERE ..." would fix the problem.
