Hi, would it be possible to allow for custom Library locations?

I don't want iTunes to back up my ebook collection, as it is entirely unnecessary. As it stands I have a softlink as follows :

Library -> /var/Media/Stanza/

Media is where I store my comics and now my eBooks.

Now, this is fine and I would be quite happy doing this, but Stanza doesn't like this redirection when importing from my Calibre library. For some reason it fails to create folders. Because of this, I must ssh in, find the folder where stanza is in Applications, remove the redirect, create the Library folder, move the entire library back, import the new books, and move it all back again.

All I ask is perhaps either an entry in a plist somewhere defining the library location or (via an option) moving it to a location where iTunes doesn't automagically back it up.
