I think numpy will work for 3.1 as well (I don't know about 3.0, but
my understanding is that there is no point into even looking at that
release).

With the scipy conferences going on, it will certainly be a good
occasion to synchronize a bit faster - nothing beats face to face as a
communication medium after all :)
