I'm not quite sure.
One way to do it is to use 1 class as the client and integrate the class
into the current mesh box (neighbourhood.py). This would probably mean that
normal sugar activities could use this 'new protocol'.
An other way would be to use a web activity as the client. I'm not sure how
exactly will I have to handle the activity -> sugar communication and pass
If going with the second approach I'd have to rewrite the whole
One of TogetherJS's features is to follow your friends around pages. I
think it's limited to a single domain, but I believe I can use it.
I believe that the first approach would be easier, but with all this talk
about new frameworks for web activities and going multi platform, I'll
choose the second approach.
