My first question would be why are you using several font-ends at all? That makes things more 
complicated than needed. In the normal FE framework, you can define either several equipment 
served by one frontend, or even one equipment linked to several devices. In the MEG experiment 
we have one slow control frontend controlling ~100 devices without problem. In the old days there 
was a problem that some slow devices could throttle the readout, but since the invention of multi-
threaded slow control equipment, each device gets its own thread so they don't block each other.
