Please note that during a discussion this week, we decided that instead of all carbon servers running on the same ports, each of the 5 products will have their own well known ports. For example, APIM GW port will be 8084 (just an example). So while we would still have portOffset support, we won't need to specify the offset when running multiple products on the same machine and they will be able to discover each other on these well known ports.
