But why stop there?  Wouldn't we also need a setting, "Stream all 
recordings from specified backend" (and associated, "Backend to always 
stream recordings") for those users who have their NFS set up on a 
non-master backend (after all, the master backend is the busiest 
backend, so may not be the best choice for a high-performance software 
RAID'ed file server)?

But, in general, hacking the DB data directly is not the approved solution.

And, really, have you tested to see if the "inefficiency" of having the 
remote backend reading from an NFS server and then streaming to a 
frontend is /really/ a problem?  Or are you just complaining on 
philosophical grounds?  (I doubt it would really be a problem with any 
switched network--though I'll admit it would be a problem if you use a 
hub, but the hub would cause many other problems, too, so you shouldn't 
use one with a Myth system.)

And, really, if you've got NFS mounts on /every/ single backend, how 
much harder is it to replicate those mounts on the frontends, too?
