I'm not sure if that's what he wants:
the channels of this second IOC would be provided under a differend CA 
port number.
To access channels from two IOCs with different CA port numbers, you 
need to provide host and port number in the EPICS_CA_ADDR_LIST.
Each application should be able to access channels of every IOC, 
shouldn't it?
If that's the case, the suggestion is not feasible.
