For what concerns "biggus" library, for working on larger-than-memory arrays, this is really interesting, but unfortunately I don't have time to test it at the moment, I will try to have a look at it in the future. I hope to see something like that implemented in numpy soon, though.

You may also want to look at carray:

I"ve never used it, but it stores the contents of the array in a
compressed from in memory, so if you data compresses well, then it
could be a slick solution.
