I personally would prefer not to do that.  My main non-administrative
interest in this mode is doing things like benchmarking protocol
overhead.  I'm OK with not supporting (and optimizing) for single user
code paths but I don't like the idea of building walls that serve no
purpose other than to make it difficult for other people mess around.
Just document strenuously that this mode is not intended for
application bundling and move on...
