I recently learned about FLIF (
http://flif.info/) which is a very nice
compression scheme for 2D image data. Unfortunately, it doesn't support
stacks and metadata but it seems to perform better than most other
compression schemes on a wide range of images. It could be the core of
a nice compression solution for scientific images. Unfortunately, it
doesn't seem like any compression scheme is going to deliver better than
about a 2-fold space savings.
