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