Technically it will be found if the corresponding .py or .pyc is in any 
of the directories (or other importers) on sys.path.

This is correct.

Well, obviously with #include you could include a path in the file="..." 
or virtual="..." string.

You will need to ensure that sys.path contains an appropriate directory 
to find modules you wan to import. Since you want to use "import" the 
files must be pure Python, you can't import .ASP pages (but, as you have 
discovered, you can include them).

IIRC I did some experiments that showed me that under suitable 
circumstances the Python interpreter will see an updated module after an 
ASP page performs a reload() of the required module.
