RESTful admin with different namespaces

Has anybody run into this need?? Excluding the goary details, I would like functionality similar to the blog example found here:

Let's say:

/admin/posts provides admin functions for: /posts

I would like:

/admin/posts or /admin/ns/posts to provide admin functions for: /ns/ posts

where "ns" is some arbitrary namespace.

Any ideas??

Thanks
