How about generating the IDs with an fixed offset instead of an multiplier?
EDIT: On second though I dont think its that easy, you might have to discard the old IDs alltogether and give new IDs, counting upwards from the offset.

Be aware that I did not read through the whole documentation yet, so the below could be moot:
Maybe it would be nice to have some conventions what ID ranges to use for certain stuff. Eg. Half the usable range for PEQ itself. A well sized chunk for imports from Cavedudes and other databases(are there any?). And the rest for local server customizations.
I recon it would help server admins to make sure that their custom additions dont clash with further updates of the PEQ databases.
