Is there a Word-like real-time collaborative word-processor that can be installed on a private network

Question

I am looking for a tool where users can work collaboratively in real-time on a mutiple documents, but that can be installed on a private network.

Basically a Google Docs like environment that can run on a private network.

I have found tools such as SubEthaEdit and Gobby, but they are geared to coders whereas I need a rich-text editor.

Answer 1

Corel's Wordperfect Lightning is a free, lightweight collaborative word processor.
