There surely will pop up issues with the API. They did for glame - and
this is the reason one can expect a major overhaul of the interior design
of the glame API.

Another question regarding to the pulgin API or the general structure of
supported networks: How can one handle feedback
- inside a plugin (without copying to a "local" buffer)
- from different plugins, i.e. plugin 2s output is fed back to plugin 1s
  input?

Have a look at
http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/glame/src/filter/echo.c?rev=1.9&content-type=text/x-cvsweb-markup&cvsroot=glame
for how to create an echo effect (i.e. internal feedback) with the glame
framework without the need to copy any data (apart from copies needed to
do modifications, of course).
