Hello,
Thanks to Manuel Quiñones, I was able to check out in detail a Mozilla project - https://togetherjs.org TogetherJS is a javascript library for... well, collaboration. It consists of a client side and a server side. The server side acts only as a bridge between clients and it repeats the messages it recieves. It's nothing complicated, nothing interesting, I'll ignore that for now. Once in a TogetherJS session, users can communicate with each other (there is a chat offered by TogetherJS). User's pointers are also shared (if desired). There also other features like audio chat and video syncing, which are somewhat experimental (by what I understood from the docs). More importantly, except these features, the library comes with an API, which will allow web activity authors to sync different objects from the page. Everything is controlled by javascript. I've already started on integrating TogetherJS with sugar. In order for two users to be in the same session, they must share one togetherjs ID. I've based this ID sharing on telepathy - like the current activity invites are sent. After having the same ID, the session is then supported by the upper mentioned server. Mozilla has offered such a server for public use, but I do not think that sugar should be using it. I think that it would be best if this is handled via telepathy, just like the current activities communicate. As mentioned above, the server has no special role other than receiving messages and sending them to all participating clients. An alternative would be to host such a server for sugar's needs (the server is a single nodejs script). I do not like this way, as it would cause web activities to depend on an Internet connection. I hope that by the end of the week I can show a web activity having collaboration support based on TogetherJS.
