Well, I compared the FW version with the B&N version and other than a couple of whitespace formatting differences in the OPF file and the addition of a nook-specific tag in the OPF file, the contents are identical. The difference is that the Nook version is uncompressed while the FictionWise is compressed. So... If they are DRM-free and you want to shrink them, you can extract them and re-compress them.
