Colin, I don't see an open community Wiki-like structure ever getting
vendor support. There is just too much exposure to unchecked, and
potentially unfounded or even malicious criticism. We do not live in
such an egalitarian society that vendors locked in tight competition
might not try and get an edge in new product adoption by spreading FUD
over their competitor's offerings. In a world where NDA's are required
just to obtain data sheets I find it nearly impossible to believe
vendors would expose themselves in such a public and difficult to
control way.
I think that if anything is going to come of this it would have to be
either of the form of: a. Voluntary vendor disclosure of standards
compliance or b. Vendor participation in compliance testing by an
accepted neutral third party such as a standards committee (as neutral
as those can be).
Best regards,
Steve
