You're asking to package up a complete software ecosystem on top of a
POSIX emulation layer on top of a non-POSIX OS. Any which way you slice
it, this will not fit the "easy" qualification you put there.

Yes, there's always someone with an idea and no, I don't blame them.
I've once thought it might be a neat idea to install Cygwin into a
virtual HD image and distribute it among multiple machines this way.
Even though I think I've enjoyed much tighter control about those
machines than you seem to be able to, it turned out to be impractical.

Provide your own local Cygwin mirror and an install script to
consistenly chose the same set of packages. Make sure your users update
when you update the mirror.
