One of my largest frustrations with desgining ePUBs has been the difficulty of decompressing and recompressing them to edit the CSS. Today on one of the groups I work with I was sent this:

Because of the problem with the mimetype-compression, rearchiving is on the Mac only via Terminal or via script possible.
One Script is called ePUB Zip 1.0.2.

This script works very well. Just Google it, and download it. It would be a lot better if this could be done within InDesign, but until that happens, this works fine.
