My understanding is that the main thing that it affects at the moment
is access to the Keychain. If you break the signature, I think users
will be prompted to enter their password whenever they access the
Keychain. There are also implications for when upgraded applications
try and access the Keychain. The other thing that it affects is the
parental controls but I don't know the details. You can change the
behaviour of your application by using the Kill flag (IIRC) which will
prevent the application from running with an invalid signature.
It wouldn't surprise me if future releases of OS X make more use of
the code signature.
By the way, you should post code signing questions to the apple-cdsa
list rather than the Cocoa list as you'll get a better response there.
