Currently using XOs to teach electricity and magnetism to 6th, 7th, and 8th graders in India.
I'm currently chronicling usage and lessons learned in the following ways: 1) What its like to be part of an 'unofficial' OLPC deployment 2) How to teach interactive science on the XO 3) Field issues with more than 1 but less than 20 laptops (something that seems to fall through the cracks)
We're using 5 XO laptops that came out of the G1G1 program.
We could use a few more, as classes are 8-10 students and we would really like a One Laptop Per Child ratio (imagine that!)
Please email if you're interested or able to help!

I'm also interested and looking for a solution for powering the XO off of a bicycle: http://wiki.laptop.org/go/Talk:Peripherals/Bicycle_Cassette http://whereisholden.blogspot.com/2008/04/bikes-ultimate-in-personal-transport.html
