Plugin idea: download ebooks from Project Gutenberg if a url relation exists

[dns53]

Project Gutenberg is a source for public domain or freely redistrobutable ebooks.
Musicbrainz contains recordings of audibooks and works representing the text of the book.
These works can link to project gutenberg with the lyrics page relationship as this site has been white listed.

If the relationships exist download the text in the users prefered file format.

Copyright issues should not exist as all files added to the site need to be public domain or placed under a licence that allows it to be freely redistributed.
