  C*-bundle dynamical systems are introduced and their r\^ole within the theory
of C*-subalgebras and Fell bundles is investigated. A C*-bundle dynamical
system involves an action of a 1-parameter group of "spatial automorphisms" of
the C*-bundle together with a notion of covariance with respect to the
diffeomorphisms of the base manifold, and turns out to define a class of
examples of Arveson's $A$-dynamical systems. An embedding invariant for
non-commutative C*-subalgebras (equivalent to a groupoid 2-cocycle by
construction) emerges and has presentation analogous to a partition function
towards a potential algebraic formulation of quantum gravity.
