Sounds good to me too. I'd also suggest storing all the incoming clicks in 
RAM and then drawing them down to disk - potentially on a different 
machine.

When you get to 10,000 hits/per second consider using memcached as a 
distributed queue but in the meantime a MySQL heap/RAM table should scale 
up some of the way.
