Hm, just can point in a direction: repository-CLONES:
http://code.google.com/p/prs-plus/source/clones
I never got behind this. For me the 'normal' repository is working like a charm. Maybe you will get some knowledge over this part...

Edit: Booklist:
The mentioned revision of quisvir IS in the DEFAULT repository. Automatic collection switching on the home screen works. But it seems that there is no manual possibility to switch collection to cycle through:
-Open a book from a collection
-Home screen shows next books in the same collection if there IS a next book
-If there is no next book in the collection, next book of the collection is shown, the actual book is in too.
-If there is no next book in another collection for the actual book, nothing is shown.
