I'd like to be able to mirror the will/did messages from otherclass in this class. I'd also like to make sure that I don't update data twice in observeValueForKeyPath:ofObject:change:context:, once on the willChangeValueForKey and once on the didChangeValueForKey.

I think willChangeValueForKey: just gives the any NSEditor's the chance to finish their editing (anybody confirm this?) -- it won't send out a KVO change notification.

Have you tried calling [self (will/did)ChangeValueForKey:@"property"] from inside your observeValueForKeyPath: method?
