Collaborative Blogging on Ning

I have created a Ning network for a group who are interested in learning more about a single topic. We are trying to embed our blog within our ning account so each user can submit a blog via ning without requiring to log in and add each user to the blogger administrator. Does anyone know if Ning are doing this yet?

The same concept would be really useful for many other social sites such as youtube, vimeo, twitter, and the upcoming googlewave which would all benefit by enabling ning to add these as apps, in effect by becoming a collaborative submission space for many social sites from the same organization, group, or class.
