Themis/Prometheus is intended to be a school operating system which provides a simple and secure networking and education solution, but still lets the user personalyze and most importantly use his workspace. The motivation behind the OS is to make a free operating system, so the students won't be "tainted" by commercial OSes which are usually sold to educational institutes for a much lower price, so the students are forced to use it. For more information about the name and the philosophy of the OS, write me an e-mail or wait 'til I finally write that FAQ-page.
