Well, LV2 is never the *cause* of this, it's an inherent problem to

BTW, I don't know if LV2 supports this, but
if it allows plugins to
*SAVE* non-generic (that is to say, session specific) data wherever
they want on the filesystem, then that, IMHO, is badly broken. There
its not always LV2 that is the cause of this. consider the SFZ file format. it refers to other audio
samples. it
doesn't require that the references use absolute paths, but they can.
so now create a plugin that allows the user to alter what samples are
used for various note numbers or velocity values or whatever (i.e. a
reasonably capable sampler) and ask it to save its current state. it
gives you an SFZ file to stash away in a location of the host's own
choosing. but what do the contents refer to?
Yeah, this problem sucks. The only solution is for the plugin to map
the paths inside that SFZ file.
It is (inherently) necessary for the plugin to map *ALL* paths in its
state for this to work. If they happen to be in some pre-existing file,
well, that's probably going to be pretty annoying, but you have to map
them all the same.
