I'm afraid neither of us has worked on it in about 2 months.  Mike
just moved and I was busy with numerous Sage Days workshops.   I will
also personally have little time to work on it for the rest of this
summer.   Nobody else has worked on port yet.

That would be awesome.

Yes -- http://cygwin.com

There is this page

        http://trac.sagemath.org/sage_trac/wiki/CygwinPort

the contents of the sage-windows mailing list

        http://groups.google.com/group/sage-windows

and nothing else.

It's more complicated than that.  It does not fully build, but if one
swaps out a few spkg's for slightly modified versions then it *does*
fully build.  Moreover it runs and passes most of the test suite.
This page (http://trac.sagemath.org/sage_trac/wiki/CygwinPort) lists
the 13 tickets I made for doctest failures -- I think they are nearly
comprehensive.
