posix on nt/2k/xp

I bumped into this by accident, and thought it could be useful:
http://winntposix.sourceforge.net/

(it seems more performant then f.e. http://pw32.sourceforge.net/)

I read the plan was to reuse the cygwin installer: wouldn't it be better 
to reuse debian-installer instead of trying to reuse a completely alien 
tool? Cygwin's installer does a lot of work for retrieving and 
dependency resolution that may not necessarily map very well to what 
dpkg/apt-get does. And debian-installer is supposed to be very modular.
