It's TCP. It's always point to point. There are no broadcast ability in 
TCP. However, there is nothing preventing you to have multiple TCP 
connections with the same local port. It's still separate connections.

Maybe we're talking past each other here?

It is very common that you have a service that listens to a port, and 
which accepts multiple connections. Think http for example. Multinet is 
no different.
