Just allocate an extra buffer for each port when creating the port.
The extra memory used by this doesn't matter. But maybe for your
usage, it could, so perhaps there should be a compile time option to
disable it.

Sorry, but I think this is pretty trivial.

This doesn't seem like a useful feature.

I don't think people should be using jack for these things, no. It
probably makes far more sense to use a DAW if you want this. I'm just
pointing out an obvious feature in jack which is missing. The way to
insert clients to set the output volume of clients is not good.
