I assume no one is using the machine who will be freaked out by the
setup app appearing on their screen.

You only have a problem in two cases:
1) The update will clobber an executable you are using (e.g. bash or sshd)
solution: somehow schedule the update & exit out. You may also have to
schedule a shutdown & later re-start of cygserver.

2) You want to add new packages
Here's the route I would pursue: Create your own cygwin repository
(say, http://foosite/cygwin) with a uniquely named empty package (say,
"foo") in the "base" category. Make foo require all the packages you
want, and make sure all the remote machines have foo installed.

Any time you update foo, from the remotely logged in CL run
$ cygstart /setup.exe -q -n -s http://valid-cygwin-mirror -s
