... and have it as a rezzed prim parameter so that only the prim having rezzed the other prims can address directly (and in a totally secuured way) the ones holding this pin number.
Use case :
  • derez all the builds holding a certain PIN number without needing to know their UUID, for example with llDerezObjectPinned( integer pin, integer flag );
  • send / upgrade scripts the same way
  • etc.
i-e it's like having created groups of rezzed objects linked to their original rezzer prim.
PS: llDerezObject() is a "stupid" function till now as UUID changes except if the rezzed object is NO COPY so you can't rely on the original rezzed build UUID. It means that you can't easily derez a full build area i-e with furniture in just one function call. Anyway, it is not capable of any native area management.
