A few moments of thought should make it clear that PPP multilink is
the only mechanism available for load-balancing outside of the
individual application.  There has been some debate about creating a
lightweight session layer for IPng which would allow this as one of
its benefits, but anything else has to be done in the link layer, and
there's only one link layer with a standard way of doing it.

You'd probably like even less the idea of multi-link PPP for
preemptive priority queueing.
