This is a great idea, where it should be easy to make a general
library for other hosts (not necesarrily running Qt) making use
of those UI's with the help of some ipc-tricks.
The great question is: Does there exist many ladspa-ui files?
In case there are, the motivation to make such a library is quite high.
Mathias, I have CC this to the dev-list. If you answer, please
only use the dev-list.
