That is not guaranteed to be unique, and I know of at least one case in

practise where it isn't (various blop packages have a different library

name).  There's no reason whatsoever the library name and label of

various LADSPA plugin distributions can't be completely different,

neither one is an ID.
Of course, the numeric IDs are screwed up for a few plugins in reality

as well, but at least that is actually defined to be an ID (therefore

those plugins are broken).
Perhaps the LADSPA spec /should/ use that (or whatever else) as an

identifier, but it doesn't.  It is an extremely bad idea to pretend a

spec says what you wish it did and implement that instead of what the

spec actually says.
I know because I blindly heeded this advice in the past, and it screwed

me :).  Please don't advise people that this is what a LADSPA

implementation should do...
