As I understand the above, you listed or implied 3 paths other than you
completely giving up, which you are not ready to do yet.
1. You release non-interoperable binary, with a modified name to
alleviate, but not prevent confusion.
2. You get some sort of help from someone to release an interoperable
3. The devs drop msvc (wink missing ;-).
Not surprisingly to me, people on pydev followed herring #3 to explain
why not. If you want responses to path 2, a post leaving out 3 and
giving more detail might be more successful. All I could do is unzip
stuff into a temp directory and run the test suite on my XP mechine.
