should start at 1 and count up as it already does. Also, instead of changing the current numbering system, could using a hash provide you with the same result you're looking for? I would think hashing the first X MB of a recording would suffice to create a unique identifier.
If you want a UUID, use a real UUID. (People using SVDRP by hand probably won't like that...)
