I answer for current soundbox API.

The soundbox (using properties negotiated with its client/user and link
request).

I don't understand what you mean. Please define "associate".

> 3) are multiple connections between ports allowed?

i.e. soundbox that read or write to the same area of other soundboxes?
Yes.

i.e. more than one flow to/from the same port?
Yes.

There may be some variants negotiated between client and soundbox.
soundbox say what it can do, client say what it needs.
