Here is an(other) idea if anyone is looking for a project:

When using a db for the meta data, there is no need for the filenames
to have the message number in them.  As such, one can use a mix of the
${UNIQUEID}, (the hostname or ip if a networked fs), and any other call
details of interest as the filename.  Or, for even nearer certainty of
collision-proof-ness¹ you can use the base64² of the sha hash of some
entropy and the call's ${UNIQUEID} for the filename.

The message order can be kept in the db table with the rest of the
meta data.

¹ (don't you love neologisms) 
² be sure to use a filesystem-friendly version of base64
