Sounds cool.  Haven't tried it yet though.

Forgive me if I'm being obtuse but why would you believe that Cygwin, a 
layer on top of Windows, would be quicker and more capable than the 
underlying Windows O/S on which it relies?  To access the file systems
you list from Windows or Cygwin, you need file system drivers, but you
know that since you're delivering them with your product.  So how do you
see Cygwin fitting in here?  Don't get me wrong.  I like Cygwin and like
to see others using it and extending it.  But I just don't see how your
stated goals under Cygwin are easier to achieve than under Windows.  
Perhaps you should restate the problem and how you see Cygwin as the 
potential solution.
