Please add links to any other pages with use cases here. Please include the source of the use case. Real world feedback from end users is preferred.

Under Tree Case

There must not be any other XOs turned on and within wireless range

Load build 656 (703 and 708 also cases) on all 10 XOs

Collaboration Examples

Uruguay Teacher Example From http://lists.laptop.org/pipermail/olpc-sur/2008-May/000118.html

- The class has 10 - 25 kids in the second grade each with an XO. There are 100 - 200 Xos in the school. Each class can join a different channel and time share to keep the number of Xos per channel to a minimum.
- One class (10 - 25) connects its Xos to the mesh (they do it by clicking the round mesh icon but they will do whatever works)
- One kid opens write (also want to use paint) sets it to share and starts writing.
- In the neighborhood view the other students see the write icon and join the activity by clicking on it.
- All the children start to write text and add pictures at more or less the same time
- Each kid wants to save the file in their own journal at any time (this is where it crashed when they tried it with write)
- After saving to the journal they want to see the shared document again. Its OK to require them to leave the share to open their own local copy as long as it doesn't "crash" if they do it out of order (what is supposed to happen if you are sharing a document then open a new one too?)

Add to release notes as needed based on test results. - There is a wireless access point in the school and they see several other wireless Aps so there is some RF background.
