What we do (thanks to Mark Hammond), is change PC/python_nt.rc to
create a new registry base for our python:

//#define MS_DLL_ID "1.5.1"
#define MS_DLL_ID "QuickStep"

Then we create path and module subkeys under that, all of which point
to our install directory.  We then copy all of the (many) needed .pyc
files (and the .pyd, etc.) into the install directory.  We don't ship
the .py files by default, but I do have another kit that adds them.

The advantage of this is that our app is independant of whatever
version of Python may also be installed on the machine.  The
disadvantage is that we need our own compile of the main Python dll.
Actually, we could probably get by with just editing the official
dll's embedded resources, but that makes me queasy just thinking about
it...
