I'm trying to put together a project to do the same thing. I'm curious, what educational software do you install? My goal (at least initially) is to supply K-8 schools with software to teach math, reading, science, history, geography, civics, and all the other basic concepts, at a grade-appropriate level, as well as programs to make the teachers' lives easier. Grading packages, lesson planners, and so forth. In my preliminary research, I've found several programs and packages, but I haven't been able to assemble an all-inclusive set. Either the reading program is only configurable up to 5th grade (for example), or the math program teaches basic arithmetic, and I can't find a pre-algebra program, or whatever.
Any insight (and links) would certainly be appreciated.
