Good and not that hard. We already have some DSH input/output-layer for 
xvid, for which I do nightly mingw snapshots.

please not. I prefer real compatibility.

we had dpkg support before. I wonder where this went. This might be an 
option, but setup.exe requires pure tar.bz2, with some automatic preinst 
and postinst scripts in /etc/

I see. gem is somewhere else at sf.net.

mingw is technically fine (besides it has no ipc layer).
The main cygwin advantage would be a wide audience, since
cygwin comes with an easy package manager: setup.exe

and it would be similar to the debian package:
one click install of a lot packages.

another minor problem:
cygwin ships with tcl84, pd has 83 bundled. we would use 84.
any technical problems why you didn't switch to 84 yet?
