well I think you just have to look at the path printed out to see that something is wrong. There should
logically be no path elements starting without the prefix c:\Python\ZOPE_2_5_0 as that is my Zope home. The
other path elements creep in because of the win32all registry paths.

I'm not doing anything here except running the python.exe that came with zope. If the path is wrong in
zopexxx\bin\python.exe there's not much I can do about it except to try and eliminate path elements in
which I'm not yet doing.

When I run zope it's via the standard service mechanism. Using procexp I can see mixed pyds if I don't
eliminate the registry path.

Certainly in the past I had different versions of python from zope and installed and they coexisted.

It seems to me that python should allow a registry free startup somehow and then the pythonservice could
pass that flag to the service.  

My feeling is that in there ought to be something like

sys.path = filter(lambda p,swhome=swhome: not p or swhome.lower()==p[0:len(swhome)].lower(),sys.path)
but it seems hard to guarantee that we get the right sys unless we mess with imp et al.
