I was thinking that the _q_lookup, for this particular Directory,
would end in a *arg.

The bottom line is that this behavior is easy to have in quixote
if you override the _q_traverse() of your directory.  That method gets
the path, and you can do whatever you want with it to make
a response.

The other problem is that the _q_traverse would need to be change
to consume exactly the right number of components from the path.
