  By comparing entanglement in emergent gauge theories to the bulk in AdS/CFT,
I suggest that the Ryu-Takayanagi area term is an entanglement edge term
related to a natural measure on the gauge group. The main technical result in
this paper is an argument why the "extended Hilbert space" definition of
entanglement entropy in a lattice gauge theory is applicable to an emergent
gauge theory.
