	This function shows the recommended way that your application

	Since these routines patch traps which change the behavior of
	the OS, it is a good idea to avoid installing them whenever
	possible.  Ideally, your application will only call the
	function 'InitialAESend' when it knows that it must start a
	new session (i.e., it has a new address that it has never
	messaged to before); at other times, it should call AESend
	directly.
