My approach is pretty much what Andrew describes. Only difference is that I'm using (so far) the files in the exact same format as DejaPIM. Also, instead of a daemon noticing the changes, I do that through a cp command.

Again, this is a personal project, so I can make it to myself as easy (or hard) as I want it to be.

However, your comments may shed some light on different ways of approaching the problem.
