As described in <http://cygwin.com/acronyms/#PPIOSPE>, it's almost always
better to post to the list, unless private email is specifically requested
by the other party.

Cygwin setup.exe supports a variety of command-line options.  Googling for
"cygwin setup command-line options" should unearth a list (or run "setup
--help" and examine the file setup.log).  You might have better luck with
newer setup snapshots (from <http://cygwin.com/setup/snapshots>).

Selecting packages might be a problem in your situation.  There's an
experimental patch for package selection via the command line -- search
the cygwin-apps list archives.  If you are willing to setup a mirror site
for your users, you can use the empty package with dependences trick that
I posted numerous times to the Cygwin mailing list (Google for "cygwin
automated install").

There are too many variations for this to make a concise FAQ entry.
Perhaps a chapter in the User's Guide?
<http://cygwin.com/acronyms/#SHTDI> and <http://cygwin.com/acronyms/#PTC>.
