We don't really need to consider hosts, do we? Just listening sockets.
If our concept of host sucks and is confusing, it should be good to get
rid of it.

Okay, you've got a point here.

Okay I see. It's either vhost configuration, or central, or I don't know

I take it that for you, of all I said, separate options just are the way
to go...

So two consistent items among access outputs. Even then, the access
output paradigm might not be the pinnacle of stream output syntax.

Okay. I'm glad that you say that now because when I mentioned it earlier
you dismissed it.

If people like using ports rather than paths, let them do it. (And
some do.) But if you want a more rational reason for doing it, there's
broadcasting a live stream on different ports to reach people who are
restricted by firewalls. And yes, I've seen that.
