Anyhow, sometimes we need to let competitive efforts develop and then let the market choose among them. Artificially stifling serious constituenies from pursuing credible alternatives is often poor engineering and worse politics. In this case, there really was significant effort to get some amount of collaboration between the two groups -- the related MIME multipart constructs were designed to allow some co-habitation -- but it didn't get any traction. (One of the groups was particularly political in how it managed its activities, but neither group was all that flexible.) FWIW, it's unlikely that the competition in this case has had anything to do with the poor uptake of either mechanism. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
