I'm a bit unclear on the difference between "N.2 Anonymous response endpoint not used" and "Non-anonymous response endpoint used". In particular we require a [reply endpoint] if the MEP indicates that a response should be expected so I wouldn't expect in-out to fall under N.2 at all, it would either be N.1 or N.3. What am I missing ? Marc. On Nov 14, 2005, at 12:18 PM, David Hull wrote: > This may or may not be behind the "don't go there" door.
