Gobby

Using Gobby is easy: just create a session, then other writers may connect to your host and subscribe to any publicly available documents in the Document List dialog, and/or create a new shared document. Files are opened in tabs in the main window, so that the user can edit them simultaneously. Any user can contribute with his own set of files to the pool of shared files, just like the session owner, and anyone can save a local copy of them. Ubuntu founder Mark Shuttleworth told us he uses it , why not you :) ??
