I think there is some big misunderstanding: soundbox API is an
application API.

soundbox *implementation* would use soundbox API for talk with internal
(nested) soundboxes, *and* a whole different set of helper functions to
do soundbox connections and other stuff needed for internal
implementation.

I've written that this a view from the opposite edge of LADSPA (or even
LAAGA, if I was sure to understand exactly what it is ;-)

I wanted to focus on an external API suitable for talking with hardware,
plugins, complex audio components, control panel, visual scopes, etc.
taking in consideration all needs (multi threading/processing, parallel,
N/M connection, lowest memory footprint, etc.)

Immediately after some agreement on the external side we can write down
the internal side design of soundboxes.
