Let me repeat. Last September, if not before, Guido identified numpy as 
a top package blocking moves by other packages and projects. I am not 
sure what he thought, but I consider it number 1. He encouraged the 
numpy people to produce a 3.x version even though some did not see any 
personal benefit. We supposedly will see numpy for 3.2. If we actually 
do, other dominoes will fall into place.

I you have any other ideas about other top blockers, please share them.
