Gobby: a collaborative text editor

Gobby is a free collaborative editor based on libobby, a library which provides synced document buffers. It supports multiple documents in one session and a multi-user chat. It runs on Microsoft Windows, Mac OS X, Linux and other Unix-like platforms.

It uses GTK+ 2.6 as its windowing toolkit and thus integrates nicely into the GNOME desktop environment.
