This seems like an _extremely_ fragile approach. Perhaps the different servers should host slightly different versions of the app, with the server identity encode within it. Or the servers should host an archive that includes the app plus a configuration file next to it that the users can drop onto the app to configure it. > The Mac OS adds quarantine info to downloaded files.

Are you sure about that? I haven't tested via the Launch Services API, but I know that the com.apple.quarantine extended attribute is not removed from the file(s) in modern versions of the OS. Rather, the system modifies a flag value within it and also records the fact that the user approved the launch in a system database so it doesn't ask again.
