There is a simpler method. Simply delay any directly heard packets 15 seconds when operating in satgate mode. If a local station successfully digipeats, whether through you or through another satgate, then the digipeated packet will make it to ariss.net before the directly heard packet. Putting this into APRSC would make it useable as a satgate everywhere.
