I have a possible solution for this problem.
Sounds OK to me, but if I knew much about this area I'd have covered it in the PEP :-)
One question: Should sys.extinstallpath be set for all platforms? Cleanrly, nothing but Windows will use it at present, but is there a meaningful value it could have on other platforms? If so, exposing it uniformly seems sensible.
