My plan is to add the ability to attach a complete set of meta
information to each stream. Besides a "class" (which i called "role")
this would be among other stuff:
This set of course would be extensible, a little bit like X11
properties. The properties we already have (like the name) should the
be folded into this set of properties.
This information can be used for a10y stuff, for "window managers for
sound" and for fixed policy routing.
As next step we would than add some kind of policy language which
could be used to specify the routing of streams. I envision something
similar to HAL .fdi files, though hopefully easier to optimize.
But anyway, right now I am focused on the real-time lock-free
stuff. This stuff is probably th next thing I will focus on.

Everything that is more than simple bug fixing should go only into the
