OpenDoc was never going to get widespread adoption, there's little attraction for developers. MacOS Services offers a more lightweight means of adding capabilities across applications. The LinkBack project http://linkbackproject.org http://linkbackproject.org is/was a better way for developers to integrate content from other applications into their own. A user can paste content from any LinkBack-enabled application into another and reopen that content later for editing with just a double-click. Changes will automatically appear in the original document again when you save. I think a lot of applications that once supported it no longer do, as Apple's security enhancements have required some big changes in the implementation.
