five.localsitemanager will not be a CMF package and I doubt we can or 
should convince the Five and Plone people to create a product instead. 
So the canonical import will be from the Python path, not the Products path.

I don't think it would be a good idea to use different imports in CMF, 
particularly because we might change things after 2.1 and site managers 
are persistent objects.

Maybe we can use the same pattern as TextIndexNG3: The Python package is 
shipped in a 'src' subdirectory of the product. The product's __init__ 
adds 'src' to the sys.path. The code could check if 
five.localsitemanager already exists (e.g. in a Plone distribution) and 
modify sys.path only if necessary.

This is a hack, but maybe good enough as a temporary solution for CMF 2.1.
