The eClass is designed as an in-class supplement and therefore is meant to be implemented in a specific room with special hardware. In the specialized room, there will be a professor computer (master) that will be connected to all of the other student computers (slave) in the same room. The master computer will host the class and all of the slave computers will get data from the master computer. Having all of the in-class computers attached to each other this way will allow the "lock-down" feature to work. The eClass application will be standalone applications on both the master and slave computers.
The remote portion of the tool will need to be fully cross platform and allow users to view lectures from Linux, Windows and OSX platforms. This can be accomplished either through a cross-platform browser application or through a standalone application that is installed on the users computer.
