Unless one intends to provide for different carbonation levels (not a bad idea at all) there really isn't a need for a dual regulator. You can run a prodigious number of kegs off a single regulator with a manifold that has integrated check valves, or if not, the user installs in-line check valves on all down-stream gas lines, preferably near the gas QDs.
I run six kegs in my keezer from one regulator (from an external, dual regulator tank - I use the second regulator for flushing and quick-gassing freshly filled kegs). My manifold has six shutoffs, each with an integrated check valve. It all works very well indeed...
