Good idea. But remember that there is still Pythonware's distribution,
which does neither create nor require registry entries,
also if you compile from source they are not available.
OTOH, bdist_wininst installers currently do not recognize these
Python installations, which is probably the next bug.

It's my fault, I'm afraid. Didn't think enough about these things
BTW: We should narrow the TO: and CC: fields in this discussion.
I'm receiving every message threefold. What would be appropriate?
