I differ on the definition of "a lot easier" for number 1. ADDTCPIFC and STRTCPIFC do not seem like "a lot" to me.
As a developer, I can start a server program (for testing) using any unused port higher than 1024. I don't need any special authorities. I also don't have to get an IP address assigned.
I don't really understand 2. Not arguing with it, I just don't understand it.
In order to bind to a port from 1-1024 you need to have special authority. In the unix world, that's restricted to root. I'm not sure what authorities are needed on IBM i.

I may have diabetes, but diabetes doesn't have me!
