Tag cloud for all pages in a book

Hi,

I have Tagadelic and Tagadelic Views 5.x installed, and I'm trying to create a block that shows all the tags for a given book (not just a given book page).

Also, I've managed to get a block working that shows tags for recent blog posts, but I realized that clicking on any of the tags lists *all* content with that tag, whether or not it's a blog post.

Is there any way to do this without creating separate vocabularies for each content type?

Thanks for any help!
