I'm sorry but I don't agree with any of these ideas.

One of the guiding design philosophies behind JACK's design has been to
avoid trying to create an API that covers every possible use case,
including all the obscure ones. We have seen several examples of this (the
most notable being SGI's graphics API) which provide the general lesson
that adding complexity in order to be able to satisfy the least common 10%
of use cases invariably causes unnecessary complexity for the common 80%.

If you want a "room" like concept then please work on providing per-port
metadata (I can post a header that describes a proposed API), because I
believe that this will provide everything necessary to do this without
JACK's involvement. This is an important addition to the API, and will
facilitate many things that are useful and moderately common.
