You'd probably have to just copy pythonv.exe to an appropriate directory,
and have it use the configuration file to find the "real" prefix. At least,
that'd be a relatively obvious way to do it, and it would have the advantage
of being symmetrical across platforms: just copy or symlink pythonv, and
make sure the real prefix is in your config file.
(Windows does have "shortcuts" but I don't think that there's any way for a
linked program to know *which* shortcut it was launched from.)
Some recent discussion pointed out that vista and win7 ntfs actually
supports symlinks. the same question about determining where it was
launched from may still hold there? (and we need this to work on xp).
How often do windows users need something like virtualenv? (Asking
for experience from windows users of all forms here). I personally
can't imagine anyone that would ever use a system generic python
install from a .msi unless they're just learning python. I would hope
people would already use py2exe or similar and include an entire
CPython VM with their app with their own installer but as I really
have nothing to do with windows these days I'm sure I'm wrong.
I've used virtualenv on Windows and it is just as useful as on other
platforms. *Most* Python developers I know work from an installed Python
although application distribution is typically done with py2exe. The
Windows msi installer is downloaded an insane amount from Python.org.

What about using virtualenv with ironpython and jython? does it make
any sense in that context? how do we make it not impossible for them
to support?
despite all the questions, I'm +1 on going ahead with a PEP and sprint
discussions to figure out how to get it in for CPython 3.2 and 2.7.
