Robotics in the Olympics (theoretical)

Since the 2012 London Olympics are in course, one thought that has been running through my head is "Could competitive robotics become an Olympic event"? Not necessarily FIRST, any competitive robotics.

A few questions I've been thinking of:

What would we need to get competitive robotics in the Olympics?
What kind of competitive robotics would be featured? (FIRST, etc.)
How would the teams be chosen?
Would the teams practice for four years, or would they just play the game from that year's challenge?
High School robotics? College? Professional?

What are your thoughts and questions?
