3) Solution without a problem? I think more people will disagree than agree with you there. As fixed gear road cycling and commuting becomes more and more popular, there are going to be more and more novices with stripped hubs and a reason to buy something better.
Again, to reiterate my (and mattio's) point - Miche already has a market standard with their splined track cogs. It's a logical progression using off the shelf parts.
Miche and Shimano are basically in the same boat.
However Miche already makes an adapter that will allow you to use splined cogs on any hub.
EDIT: If you want to say Shimano is a more popular company then yes, I agree with you. But my point is that the Miche system already exists, is compatible with any hub, and could do exactly what you propose assuming hub manufacturers choose to do so.
