A Canadian company called Userful has created an open source product for schools based on Ubuntu.
According to the company, one Userful MultiSeat server can replace 11 individual computers, cutting down on power consumption and lowering upfront installation costs.
"The company claimed that the Multiseat software reduced energy costs by up to 90 percent, enabling schools to recover the cost of their computers through electricity cost savings alone," reported Techworld.com's Maxwell Cooter.
