@Mr. X.: can you point me to some documents about the format of the .metadata and .cover files from Calibre?

They don't exist currently. For the nook color it resizes the image and saves it as the same name as the book but with .jpg instead of .epub/.pdf. It includes an embedded ImageMagick library so resizing to the small and medium dimensions and converting to png (I think that's what were in the SQL blobs?) are possible. For author/title metadata there is the xml opf file, but those are huge and overkill and not included in any of the existing device drivers. The strings themselves are, so I was just going to open the file and write the author string, a newline, the title string, newline, EOF. Maybe Author= and Title= if you want to get fancy...

W.r.t. the extra files, mdbindex can be changed to remove the extra files once they are processed. (although this might give sync-problems with Calibre).

aha. my memory wasn't inventing things. Yeah, cleaning up the files afterward wouldn't really break anything since Calibre doesn't really 'synch' devices yet except maybe the Sony's... For everything else things only happen on "Send to device" the first time. And if it did synch, writing a new cover/metadata file would be a good way to indicate to the indexer that global.db needs updating too

Yep, it's mostly my collection of magazines that have print/copy/etc restrictions on them that can't be changed. An on-device metadata editor would be an improvement over right now but still an extra step since Calibre knows what the real info is
