[Sugar-devel] [Proposal] Sugarizer School Box - GSoC '18

[Lionel Laské]

Hi Tony,

Thanks for this comment.
BTW I must say that the Sugarizer School Box that I've described for the
GSoC project is not at all what you described. At least for a version 1.

In short: Sugarizer School Box is not intended to work with Sugar and with
the XO laptop.
It's intended to work only with Sugarizer.

The reason is that Sugarizer Server use a specific way of handling presence
(using WebSocket) that is not at all compatible with the way of handling
presence on Sugar (using Telepathy).
It could be a good idea to study if Sugar presence could be updated to be
compatible with Sugarizer presence but it's clearly another project and
can't be accomplished in the same project than Sugarizer School Box.

The Sugarizer School Box is more intended to be use with a set of Android
tablet using the Sugarizer App and will work too with laptops (not only XO
laptop) via the browser. It's currently a request from our two first
Sugarizer deployments.

I think it's better to start the project by this perimeter and try to
expand it later to include specificity of XO laptops, adhoc network and
Sugar.

Best regards from France.

       Lionel.
