As tanuk correctly pointed out the infrastructure for implementing
something like this is already available in the PA core. What's missing
though is a module actually making use of this, a protocol extension
to allow client-side control of it and finally a UI for it.
It should be relatively easy to simply extend m-s-r a little to cover
this too, the same way it already controls the devices and volumes for
particular streams. The only hard part would be to keep proper compat
with older versions of the protocol and PA. But that should be
