uhm... I don't think extending sys.path to include every package is a good  
idea. You're basically flattening the directory structure. Just put all  
your stuff in a single directory if this is what you want -- if that's not  
what you want, it is what you are actually doing, anyway.
Among other nasty things, you may end up having multiple copies of the  
same module, when imported using different names.
