elijah> I am leaning toward sharejs, because I think it is cleaner and more lightweight than etherpad-lite. We don’t need/want the additional features etherpad-lite has. I think we probably just want it db-less, but it would be trivial to add mysql support. I am not a fan of coffeescript, however. In the long run, I am intrigued by the sharejs model and imagine we could make it so that all page types, not just wikis, are real-time collaborative.

Other related projects¶

Nice list of collaborative editors:

nowpad

Realtime text collaboration with Node.js, Express.js and Now.js
NowPad adds realtime text collaboration to parts of your website such as textareas, allowing multiple people to work on the same document at the same time (while seeing each others changes as they are applied). The benefit of this over traditional collaborative editing is two people would be editing the same document, they’ve both made changes, one person saves, and the other has to make the choice “lose my changes, or lose his changes”. Nowpad keeps and applies both your changes as they happen

opencoweb.org
The Open Cooperative Web Framework provides JavaScript enablement of concurrent real-time interactions among remote users and external data sources. This emerging class of applications is referred to as cooperative web applications. The framework handles remote notification of user changes, the resolution of conflicting changes, and convergence of application state using Operational Transformation algorithms. The objective of the framework is to support cooperative web concepts across all browsers and devices

gooogle mobwrite

MobWrite converts forms and web applications into collaborative environments. Create a simple single-user system, add one line of JavaScript, and instantly get a collaborative system.

www.sameplace.cc

These are not applicable, because they are desktop applications. but they are interesting examples of UI.
