you can, but it is a buffering issue... mkisofs does operate in two
passes, one to create the TOC, one to copy the files.

look for zisofs if you're looking for compressed isofs tools... it's also
used by hpa's redhat superrescue images.  (there's also even more
specialized stuff like cramfs, but it's not at all appropriate for
duplicity due to a bunch of limitations.)

there's an ext2 compression patch somewhere too... dunno how up to date it
is.
