We can start EB/ER using the daq start up script from any predefined hosts
similar to coda_roc's. The Run Control is currently using daq component 
names only (rather than hostnames).


I also think that it would make sense to have only one configuration
for each specific hardware and handle parameters (like farm settings)
through RTVs

Cheers,
