Do you want us to add Etherpad to the Bitnami library? You can vote for it on our wishlist.
EtherPad is the first web-based word processor that allows people to work together in really real-time. Etherpad allows you to edit documents collaboratively in real-time, much like a live multi-player editor that runs in your browser. Write articles, press releases, to-do lists, etc. together with your friends, fellow students or colleagues, all working on the same document at the same time.
