But 200-300 users could be online at once.

The XS is quite a complicated ensemble of software having an XS at every school magnifies the administration work. Having a centralized XS for several schools can dramatically reduce administrative overhead. Additionally our schools only have about 8 hours of electricity per day. I am concerned about the XS losing power suddenly multiple times per day. We have a relatively low latency connection b/w the schools and the XS. We have discussed these issues before and I believe that we both came to the conclusion that Nepal has different requirements than some of the other pilot schools. -- Bryan W.
