That's an interesting idea Bryan. I'd love it if the Win32 build process
was a little more streamlined but I wouldn't know where to begin myself
within the Mono build scripting at present.

In the short-term it might be possible to do something with a script
using one of the command-line package managers for Cygwin (e.g. apt-cyg)

I could have a look at that when I have time maybe if the Cygwin UI
setup app is proving a hurdle.
