Two questions regarding the domain mapping plugin

Easy question first: Does your domain mapping plugin work on sub-directory installs?

More advanced question: Can you map to a URL with a path or filename appended to it?

As an example: - MU install - MU blog_id=1 - mapped url

So if I were to type "" into my browser I would see the contents of "" as a desired result.

This particular situation won't work if I get redirected back to "" as their WWW traffic serves other content.
