A Promising Model for a Collaborative Writing Environment

As this screenshot shows, I have cobbled together a browser based environment for research and writing. I've combined Grazr (left side), iJot (right side), and the Performancing blog editing extension (bottom).
In the Grazr window one can read the feeds fed to that space through an OPML reading list maintained by a member of the collaboration team.
In the iJot window one can edit text, wiki-like, inside a shared outline.
In the Performancing blog editing extension one can write blog posts that will appear in the Grazr window (providing one's blog feed is linked to the OPML reading list, of course).
At this time this configuration does not work because a shared iJot outline cannot be edited within a frameset. Replace the iJot outline with a shared Writely file, however, and one is in business.
A third vertical pane, containing a digital chat service such as Meebo, could also be added.
