Hi Rishabh Nambiar,

The critical feature of your proposal is to provide a dedicated RPI 
method to make Sugarizer available to a classroom set of XOs via the ad 
hoc networks.
Technical skills at a deployment are minimal so simplicity is vital. 
What is needed is an image which can be copied to an sd chip ready for 
use. Ansible and other tools can be used, of course, to make the image.

Despite Sugar's emphasis on collaboration, almost nothing has been done 
to characterize performance of the ad hoc networks in sustained use such 
as you propose. You will need to make arrangements with an XO deployment 
to test your image in a classroom setting to determine how many XOs can 
be supported using Sugarizer concurrently with acceptable response.

Does it matter if all the XOs are connected to the same network, e.g. Ad 
hoc 6? Would it be better to distribute the laptops across the three 
networks? How do the laptops connect to the Sugarizer server?

You may need to have a Sugarizer icon which can be joined by the XOs, 
emulating the current collaboration mechanism. The current versions of 
Sugar show the user his own url on the ad hoc network but not the url of 
the server. It may be possible to give the server a fixed url which 
could be accessed from the Browse activity. Currently the links in the 
Browse are given by a web page stored in /home/olpc/.library_pages on 
the XO. Changing that would require each XO to be updated. 
Alternatively, perhaps each user could be instructed to use (i.e. the url of the server) and then to make that 
url the initial page for Browse. This will require simple and clear 
instructions which the teacher can provide to the students.

Most GSOC projects attempt too much and so end up only partially 
complete. This project should be mentored by Lionel Laske or a colleague 
to ensure that it can be completed and the result made available to the 
community. This is an important initiative. Currently in Rwanda there 
are more that 50,000 students with access to XOs but no access to a 
schoolserver or to the internet.
