First of all, it's "Cygwin", not "CygWin", lower case 'w', not upper
case 'W'.  Please fix that before publishing.

Licensewise it's *not* ok to put the whole distro on a CD and add it to
the book, unless you also add a CD to the book which contains at least
all sources of all GPLed packages from the distro, too.  According to
the GPL you must provide the sources the same way you provide the
binaries, otherwise you're infringing the licensing.  For a start, see
the GPL FAQ http://www.gnu.org/licenses/gpl-faq.html, or better the full
text of the GPL  http://www.gnu.org/licenses/gpl.html.

I'd rather see that you don't provide a CD with Cygwin, but only provide
the URL to the Cygwin homepage http://cygwin.com and let the people
download from the net distribution.  This way, they get the latest
available packages and bug fixes, and using the setup tool from
http://cygwin.com is really simple and straightforward.

There's also the problem of support.  Since readers of your book will
use your CD distro in the first place, they will inescabably use old
versions of Cygwin and the accompanying packages.  However, since you
will probably not have a support forum, your readers will ask on the
Cygwin mailing list for help.  The Cygwin mailing list only supports
users of the net distro, not of third party distros.  So why not let
your users just use the net distro in the first place?

As for acknowledgement, see http://cygwin.com/who.html.
