Nothing in ladspa.h says that UIDs are globally unique - just the .so +
label combination is guaranteed to be (system) unique.

Yep, and I think thier not alone. I only realised that UIDs were not
globally unique recently myself. Its kinda obvious when you think about
gnerated plugins, but its very confusing.
Using some kind of self-authorising, URI-like scheme would have been a
much better idea, but hey. Its a bit late now.
