1) Yes - Zip does accept input from stdin and write to stdout much the
same as tar (- as file name).
2) Yes - Unzip does the same
3) No - atleast I have seen no mention in the documentation of any
'special' ability to handle raw devices.
4) Yes/No - Permission are handled correctly, there is an option to
handle symbolic links, unforetunately 'normal' links are handled
as separate files (like cp). As far as I know there is no way to
handle ownership.
