But surely the GUI is bound to a certain list of plugins. So, when we
get LADSPA support in Jokosher, because we need to make the GUI for
the plugins, we need to basically decide on a list of included plugins
and create the GUIs. Surely this limits the ability for the user to
just install a plugin pack as we won't have GUI for those plugins?
Correct me if I am wrong on this, I am still very new around here. :P
Oh, and I read that someone was working on an XML DTD for plugin GUIs
- what is the current progress on this? I could not find anything out
about it on the LADSPA site.

I assume that the GStreamer bridge exposes these port hints as
gettable properties. I will check with them.

I plan on doing this. I also noticed there is dsptools which offers
python bindings to LADSPA among other things.
Thanks for imparting your wisdom Lars. :)
