Will we never want to refer to fake devices by name for testing? i.e. what if I
just want to add a fake printer to the mock service? Do I have to know that
"fake printer" is index 0?

nit: please use consistent quotes, so either '' or "" everywhere, except when
breaking convention is convenient for nesting.
