Rails - Jul 2006 - Paging with multiple tables/models

I''m looking for a smooth way to implement paging over a combination of
two tables.

My application tracks which books and movies you have borrowed from
me.  For reasons that make sense elsewhere in the application, these
are seperated out into two tables: book_borrowers and movie_borrowers
and therefore 2 different activerec objects: BookBorrower and
MovieBorrower

This particular screen will display something like this (plz excuse formatting):

Name    Has Borrowed
-------      -------------------
Ron        Book1, Book2, Movie4
Bob        Book3
Tom       Movie1

Paging seems quite simple if I would like to display either books or
movies that you have borrowed in a table but I''m struggling a bit in
paging over the combination.

I''ve played with having a seperate object that combines the two (and
is paginated), having one of my two objects select and join/union, but
neither seems completely bug free and clean.

Any ideas?

Thanks.

If it helps...
movie_borrower columns: id, user_id, movie_id
book_borrower columns: id, user_id, book_id
