To provide some clarification, the Worcester County system and Ocean City system are (and have always been) fully networked. There are no patches between the two systems as they rely on a Network Interface Module to link them at the system level. Any resource (user, talkgroup, conventional interface, etc) can operate on either system natively. With that said, users and talkgroups can be either allowed on a single site, allowed to roam between sites or "forced" onto multiple sites. In the case of the agreement between Ocean City and Worcester County all of the above situations exist to allow maximum coverage while taking site loading into consideration.
So, to answer the questions posed, while there are two systems that can each stand alone - the way that they are connected does in fact make them function as one system. As a result there is close coordination between the system with each party having blocks of LIDs, talkgroup IDs, etc available for use on their portion of the system.
