At a minimum, you'll need to put Cygwin on a partition accessible from
both systems.  You can use the "mount -m" command to duplicate the mounts
from one system to another (no need to reinstall Cygwin, just make sure to
fix up the drive letters in the resulting mount commands).

One problem I think you're going to run into is the SIDs of users in
/etc/passwd and /etc/group (and thus, file ownership).  Partly it's a
general multi-boot file ownership issue, and not Cygwin-specific, but you
will need to make sure you have the right things in /etc/passwd and
/etc/group for both systems.  Symlinks might become a problem, too.

You might find the Cygwin-on-CD or Cygwin-on-USB-stick instructions and
musings helpful (they should be in the mailing list archives).

P.S. I'm not sure I understand your last question.
P.P.S. Speaking of Linux, did you know that Cygwin runs under WINE? :-D
