Hi Charlie, I'm traveling with limited email ... so I just now saw your note. > I am almost certain they > should be considered out of scope for the document > under discussion. In looking at the reference in the charter for "ad hoc" (RFC 2501) the defined MANET is a Chimera - a mythical beast made of the parts of many other animals. It is a shame that smaller monsters are out of scope (like 802.11 ad hoc) ... Paul > -----Original Message----- > From: Charles E.
