I'm hoping that's /Library/Preferences/my.bundle.identifier.plist - if
it's picking it up in /Library that's a bug, I think.

Yes, but this will fail unless the user has permission to write into
/Library/Preferences (the average user doesn't). You'll have to use the
Authorization Services to be able to write this preference to disk.

NSUserDefaults doesn't have the ability to write per-host preferences
at the moment, so using the CFPreferencesSetValue API is the correct
way to do this.
