This refers to the Python launcher that Glynn mentioned half a year ago:

http://lists.osgeo.org/pipermail/grass-dev/2013-January/061466.html

The launcher is explained here:

http://docs.python.org/3/using/windows.html#launcher

It actually allows the use of shebang lines:

http://docs.python.org/3/using/windows.html#shebang-lines

And it allows to create a py.ini file to customize the way Python is 
called. A version of that file in the "Application data" directory 
overrides systemwide settings, so I guess we could use something like 
that to customise if shebangs are not enough:

http://docs.python.org/3/using/windows.html#customization

In my limited understanding this actually sounds like a very promising 
solution which avoids having to treat Windows in a very different way. 
shebangs with '/usr/bin/env python' might allow us to solve the issue.
