Anything that more than two "real user" entities are going to want to use, and *might want to inter-operate*, is probably standards-track material. About the only reason not to do it would be if it was decided that the design chosen was technologically flawed. However, I think NAT should have taught the IETF (as bridges taught me) that sometimes what seems technologically flawed is in fact just what the market needs and wants - usually for some reason one hasn't sufficiently appreciated. So I would generally err very much on the side of caution, and stay with the standard in the first paragraph. (Even if it does sound like an April 1 escapee...) Noel
