I would love to see that too. I would say its enough to agree on the conventions
(format and place in filesystem) and add them as a comment to the ladspa header.
In GStreamer we have a preset interface [1] for plugin and I would like to
implement that for the ladspa wrapper then. The default implementation of the
iface uses GKeyfile as a storage backend (like windows ini files). The
implementation [2][3] handles system wide data in e.g. /usr/share/ladspa and
user data in $HOME/.ladspa/.
