To me the novelty appears to be the backend agnostic RDFa communication with the content server rather than the inline editing.

Would be nice if more CMS backends would support this, followed by more and more editing frontends and tools. Thereby everyone could pick the component of their choice. Even different editing frontends for different unsers on the same system would be possible.

That is exactly the plan: http://bergie.iki.fi/blog/decoupling_content_management/

But first you have to have one nice editing interface as a carrot so CMSs start supporting the needed features.
