FWIW: actually, I don't see Jens saying that signed apps will by default run in 
a mode that enforces privilege checking, and I just spent a few minutes 
digging, and didn't find anything saying that. Are you really sure that 
Gatekeeper's "level 2"--code must be signed, but not app-store-ready--will 
enforce access restrictions? Pointers gladly appreciated, and maybe I'm just 
not reading carefully enough.
