The common way to solve this which does not cost extra database space
would be to store a unique but permanent identifier per aox instance,
and then use a one-way-hash (e.g. MD5) to make your UUIDs difficult
to guess (it only needs to fill in part of the UUID this way; the message
number itself could still be transparently present).
