well, that sounds like a job for a plugin to me.
maybe with cron, to scan a directory every 5 minutes or so, and then push them into the DB while mt-daapd is running.
Would that actually suffice, or is there more than that to make mt-daapd recognize them songs ?
Nope, that’s it. A four or five line perl script running out of cron, I think. 🙂
