Yes, it's different, meta_path is a generic mechanism
that doesn't depend on sys.path and is tried before
sys.path is traversed; the other is triggered by a
special sys.path entry (like a .zip file).

I think you can't make an import fail completely; if
your meta_path doesn't work, the next one is tried,
and then the standard places (where the error is
finally raised).
Looks like the "global name foo not defined" error:
sometimes it's not a global name at all, but that's
where the search finally failed.
