Some Categorical Considerations in Extending TQFT via Higher Gauge Theory

In this informal talk, I will look at some considerations that show up when extending gauge-theoretic construction of Topological Quantum Field Theory to connections on gerbes and higher structures. In particular, I will mention some contexts where higher categories with cubical or other more complex shapes of higher morphisms seem to recur, and suggest a few questions this raises.
