Jason,
you may also check the following post
http://blog.internetworkexpert.com/2008/01/26/ppp-multilink-interleaving-over-frame-relay/
where we explain a complex PPP multilink & interleave scenario. Athough you
usually dont bundle Frame-Relay interfaces using MLPPP (FRF.16 exists for
that purpose) the post explains mechanics of PPP fragmentation and
interleaving in details.
