Heh... long story short: LV2 uses URIs, LADSPA uses UniqueIDs (not

necessarily but...), two LV2 plugins with same URI are required to

have the same "port signature" (i.e., ports) and I wrote a LADSPA to

LV2 bridge where the URIs of the bridged plugins are in the form

urn:ladspa:xxxx, where xxxx is the UniqueID.
This means, if you change the port signature and maintain the same

UniqueID, we would have incompatibilities in the LV2 world. If you

create a new plugin or don't touch ports, instead, everything's fine.
