(rushing from one talk to another)
I'm currently at EuroPython in Bilbao where I've me Amber. I hope I can contribute to more progress on this if we get to Sprint over the coming weekend.
Cheers to all,
pywincffi is getting very close to having all the API calls necessary to replace pywin32. By my count there should be one function left, GetOverlappedResult(). All of the other functions and constants in use today should be covered and ready to start swapping into Twisted.
This is fantastic news. If we can move the build infrastructure for producing wheels for all the various flavors of windows Python into pywincffi, that will simplify and streamline the Twisted build process even more.
