What about using the *splat:

routes router.routes

The routes hash maps URLs with parameters to functions on your router, similar to the View's events hash. Routes can contain parameter parts, :param, which match a single URL component between slashes; and splat parts *splat, which can match any number of URL components.

For example, a route of "search/:query/p:page" will match a fragment of #search/obama/p2, passing "obama" and "2" to the action. A route of "file/*path" will match #file/nested/folder/file.txt, passing "nested/folder/file.txt" to the action.
