Coda allows a document to be viewed and edited collaboratively by multiple users across a network in real-time. "Sharing" is how you announce to other users on your network that you have a document that can be remotely edited.
This collaborative editing mode is powered by TheCodingMonkeys' Subetha Engine, and is compatible with SubEthaEdit. For more information about SubEthaEdit, visit www.codingmonkeys.de
