all the function pointers into a struct and then call them. Third party modules would link against this DLL independent of which
python is being used.
I believe this is not implementable: How can the DLL know which Python DLL to use?
Well for py2app on Mac OS X, I wrote an executable stub that chooses a Python runtime from an XML file, looks up and binds a few symbols from it dynamically, and then starts doing stuff. Works for 2.3 (as long as it's not compiled debug or trace refs) and 2.4 (universally, because it has exported functions for incref and decref).
For extension modules, this makes much less sense, but I wanted to be able to bootstrap Python programs with a precompiled executable that I didn't have to maintain across several versions.
