The goal would be to make the PV interface (so not the frontend, but
the ring buffer, negotatiation, etc) as OS agnostic as possible.
And as George is going through the maze of how audio systems work hopefully
the picture of the most common approach will surface.
James, would you be interested in this? As in, looking at the design
and seeing what problems it might have and also well providing ideas
of what is too Linux-y and what might be a better idea for an OS-agnostic
approach?
