Actually it is possible to issue certs with W2K that are recognized

can claim to be interoperable something odd is happening.
It is failure to interoperate that is a market disadvantage!
IETF mailing lists are not a good place for discussing, plugging
specific vendor products (although most folk feel free to correct
erroneous statements about their product like I did).
