I think the Khan Academy environment needs to be rehosted on a school server. In many deployments, schools do not have consistent broadband access to the internet. The school server provides the main storage via a 3.5" hard drive while the XO storage (1GB) can be thought of as a cached with the material currently being used by the student.
I would be very interested in seeing the exercises and profile aspects of the Khan Academy rehosted to the school server. So far the downloads that I have are limited to the videos - do you know of any way to download the rest of the site? You suggest that you have an alternate way to provide these exercises. I would certainly be interested in technical details (as an example I tried to generate addition problems involving operands of four digits or less (based on curriculum requirements, don't ask about the mathematical foundation). I discovered that random about 90% of random four digit numbers have four digits! The Siyavula materials (http://cnx.org/lenses/siyavula) are available under Creative Commons and give a representative example of textbook/workbooks that could be remapped to the XO. It is interesting that these textbooks (and many others) are very week in introducing concepts - they give no motivation, provide a couple of worked examples, and many exercises. The motivation and introduction are left to the classroom teacher. This is where the Khan Academy videos fill a real need.
