except that hdf is one big honking pain in the butt to build.

Robert's right, bzip isn't a great option anyway -- it can do multiple 
files, but it just concatenates them, and doesn't appear to provide an 
index. I used to use afio, which would zip each file first, then put 
them all in an archive -- I liked that approach. We could, of course, 
build something like that with bzip, but it looks like python's zip will 
work for >= 2.6, so no need for something new.
