I mean a plugin that reads a config file to check if a file to be bitprinted matches a template - user creatable templates; maybe a page on this site for them? - and then extracts and hashes the data based on that template.

Sorry, I was *not* totally with it when I wrote the first post, it must have been a little hard to understand.

Yes, I know an 'automatic' generic plugin would be impossible.

And yes, I know sha1 from mp3s is from the data area - otherwise, as people change the titles, the bitprint would change :-(

If I knew any C, I would write this myself. However, I don't. (I only know how to use PHP and ->VB(ugh)<-)
