Volunteers with the San Francisco Bay Area non-profit Partimus have been working to put Linux and other F/OSS software into area schools. Getting into schools is one of the biggest hurdles for anyone looking to bring F/OSS into education and can often be an insurmountable one, so the first suggestion will be that if the goal is to spread Linux and F/OSS in education is to start with an adult learning center, after school program or similar organization in the area.
