Aha! Thanks!  This has moved me on a lot, but I don't think I'm quite 
there yet:

1.  Installing Python for .NET as a standalone, and using it in the 
interactive session, all of the above, apart from 'from CLR import 
TopNamespace' works.  'from CLR import TopNamespace' gets 'ImportError: 
cannot import name TopNamespace'. 

2. Installing Python for .NET as part of my existing Python 
installation, and using it from within Pythonwin, none of the above 
works: 'import CLR'  raises a 'System.IO.FileNotFoundException' - I am 
alerted by a 'Just-In-Time Debugging' pop-up window and Pythonwin 
terminates 'in an unusual way'.

Should Python for .NET be used only from its own interactive prompt?  
Why can't it import TopNamespace and can I do without it?

Thanks again for your help. This is going to be very handy: Windows and 
.NET are alien environments to me (I work with linux and python).
