If you are honest about wanting to bring this technology to _ALL_ web users including Safari and Firefox users, then I suggest you add OpenType to the Microsoft Open Specification Promise (or possibly the Community Promise depending on what you want to
achieve). If you intend to extract license fee's from competitors using patents once they have adopted this technology then you might as well keep it to yourself.
Great talk though. I really liked the point about adopting the computers to the human eyes instead of vice versa.
