I think it would be easier to implement if it had a name, that people could relate to and almost forget "bitcoin" and think more in this denomination.
It already has a name:
The Bitcoin reference client (Bitcoin Core) officially calls it "µBTC".
But some people (including me) want to
rename it.
But my real question is: "How do we get the ball rolling. How do we make this happen?"
Have a look at my post #2 above, I think it could trigger a chain reaction.
