We're just not set up for shipping binaries. We have no mechanisms for

Depends on how much of a hacky solution you want. cabal-install already
works on windows and uses the zlib package. It already has code for
untaring packages. Adding an sdist command to cabal-install that calls
the Cabal lib prepareTree function to prepare the tar image and then
uses it's internal tar and zlib code to make the package doesn't sound
too hard.

So if there's someone who wants to have a go at that we can give
