Ok, starting to look good now. Currently ecasound searches through
/usr/local/share/ladspa/*.so, finds all unique LADSPA plugins and puts
them to a dynamic object map. To use a plugin, user must know its
unique name. The following is done with ecasound's current CVS-version
(shortly put, works great :)):
