Win32 Open Source or free .NET integration?

[Michael Kelly]

I haven't used .NET myself yet but another programmer
using it raves about the back end integration among
the languages.  Also I noticed ActiveState is doing
a Visual Python that's supposed to integrate fully
into .NET.  I know there are some open source project
for .NET for Linux/unix but I was wondering if anyone
has heard of a free Win32 implementation in the works?

It would be way cool to plug Python into this system
from what I'm hearing(but $295 I don't have.) :)
