Begining the multiple user editing

Today we finished the proof of concept for the multiple user editing. When users make an action their action is sent to the server and the server stores the data in an array of changes to send to all the other connected users. Currently only one instance of a document can be opened by any one user or the data will be split between the two browser windows. Soon in the future this will change. I am truly exited for when this features is completed.
