If not, what's the best practice here? And if I were to use some

If I understand the question correctly, then when the signal is
received, your headless app calls -synchronize on the
NSUserDefaults. This assumes you don't have any shared-access
contention issues.
Yes. The app that writes the pref should call synchronize and send its
signal, then the app that reads calls synchronize when it receives it.
I have a pair of apps that do that; I use
NSDistributedNotificationCenter and the CF equivalent
CFNotificationCenterGetDistributedCenter for the signals.
