Hobby horse time again!
One of the basic reasons I supported the development of an ISO standard for OOXML was my belief All market dominating interface technologies should be QA-ed, RAND-z standards. Once you have achieved a position of market dominance for a technology, the market for selecting between technologies dries up and needs to be replaced by a lively market for symbiotics and substitutes that use that technology. Standards encourage this. I think this is a position that many competition watchdogs are sympathetic to.
The FAT32 file system is surely another example of this kind of market dominating technology.
Like OOXML, it needs to be brought into a position of being a market-creating technology rather than a market-stifling one. Submission to a standards consortium with clear open IP access rules (e.g. Ecma in the first instance) would seem entirely appropriate, and I am sure would win a lot of continued goodwill.
