Can't this be handled with an __init__ module? Create an inet package
and having the __init__ module pull whatever it wanted into it's own
namespace.

It would be nice to then use warnings to show deprecation messages
when the old import is used (import url instead of import inet.url),
but I don't think that is quite so easy.
