They do in-fact have to be stateless with respect to the contents. They
will no doubt be created in a same distributed forwarding  engines that
currently do IP-MPLS encapsulation and L2-MPLS encapsulation. likewise
their decapsulation will occur in such devices.

Today congestion occurs on MPLS networks. intermediate hops that are
congested have no choice but to drop packets.
