Steve Burt points to SynchroEdit, a collaborative a browser-based multiuser text editor. It allows multiple users to edit a single web-based document at the same time, and synchronizes all changes so that users always have the same version. This is similar to Subethaedit, except that it is browser based. Suggested uses include collaborative note taking during a class, or back channel writing during a conference or phone/tele conference. I would like to install it at Lewis for use by teachers and students as a note taking tool. It is currently in Alpha mode, but they plan to release it under an Open Source license.
