It features a client-server architecture which supports multiple documents in one session, document synchronisation on request, password protection and an IRC-like chat for communication out of band. Users can choose a colour to highlight the text they have written in a document. Gobby is fully Unicode-aware, provides syntax highlighting for most programming languages and has basic Zeroconf support.
A dedicated server called Sobby is also provided, together with a script which could format saved sessions for the web (e.g. to provide logs of meetings with a collaboratively prepared transcript). The collaborative editing protocol is named Obby, and there are other implementations that use this protocol (e.g. Rudel , a plugin for GNU Emacs). Gobby 0.5 replaces Sobby with a new server called infinoted.
