M$ will not 'learn' from this episode; they have a "perverse economic incentive" (thanks to Bruce Schneier for that piece of terminology) NOT to adhere to truly open standards and to do their utmost to impose their kludgeware on the World.

The entire M$ ethos is to sell their wares based not on their technical merit, rather on their ease-of-use; to the vast majority of end users, the underlying technology is uttterly irrelevant.

I do not intend the foregoing statements to mean that all efforts to prevent any M$ 'technology' being adopted as any standard may as well be adandoned - the fight must go on!
