Hi Morgan, Got it, thanks!
Let me know if we have a chance to comment on the design of future tests to help align them with user requirements. I want to find a few basic cases which we can support now (e.g. 10 or less Xos is a good start) and help position the timing and details of use cases which we may support in the future. We can buy as much time as needed to rebuild this code if we set the right expectation. We just have to warn them before they start counting on things which don't work well yet. Any input on that is appreciated. FYI they put up a training on how to use the XO at: http://www.ceibalflorida.blogspot.com/ It includes two sections on mesh usage (Experiencias colaborativas) one of which has a list of activities. Let me know if you want a translation. In the mean time, they are going to have a development "Jam" in Uruguay next week http://wiki.laptop.org/go/Ceibal_Jam I asked them to try out a few mesh tests if they have enough Xos. I'll let you know if they get any useful results.

The Chat activity used currently with Cerebro isn't the regular Chat activity - it is one that has been customised to work with Cerebro outside of the existing Presence Service collaboration framework. > I ask because there is recent feedback on mesh issues from a teacher > at Lambayeque, Peru > http://wiki.laptop.org/go/Lambayeque#Inconvenientes and a teacher in > Uruguay has asked about supported Mesh features too.

Please don't tell them to use the existing Chat on the existing collaboration framework in that way - I think we can only handle less than 10 XOs on simple mesh (no jabber server) with some reasonable reliability. > The good news is they are motivated to use the mesh which helps > validate one design goal of the XO.
