Real Open Source Applications for Education?

openeducation writes: I have been researching open source solutions for K-12 education pretty heavily for the past year and have been disappointed to find no real alternatives to the large administrative applications like student information systems, data warehouse, ERP, etc. But recently, I ran across Open Solutions for Education. http://os4ed.com/ This group appears to be making a serious effort at creating a stack of applications that are open source alternatives to the large and costly commercial alternatives. Centre, an open source student information system that has been around for awhile, is part of the solution stack. http://www.miller-group.net/ They have a data warehouse and are proposing an open source SIF alternative and an assessment solution. While the proof is in the pudding, these guys have working demos and they look pretty good for a first run. K-12 education in dire financial straits and solutions like these could help with lower TCO. Plus, education is a collaborative industry already, which makes perfect sense for open source.
