Not that I know of. p4est manages the parallel octree very efficiently,
and applications are free to interpret the cells any way they like. It
is perfectly fine to use p4est for a single octree, not using the
forest-of-octrees feature, so no restriction there.

I'll be at the siam cse conference, feel free to go find me.
