Thanks. The name of the imported file will change with each user and for
each project so according to the this reference using this in my situation makes
sense.

Thanks. This worked! I was using __import__ without the other arguments
before. I guess did not think it will work :-)

The two programs are separate, there is no fear of a circular import. Also,
I need only a function to get access to the objects in the other module so
the import is inside the function... no fear of ending up in a mess.

Thanks. I guess this makes more sense than execfile and it works.
