Hey all,
I was wondering if anyone is aware of technology or applications that are used to secure content on CDs. A Scenario to clarify: School kids, instead of buying text books, teaching material (applications) can be placed on a CD or sometype of drive. This material can be read of the screen but not copied, printed or duplicated in anyway. This way the school can ensure that other schools cant get FULL copies of the applications and material. Any ideas? Even a solution such as having dedicated, specialized affordable laptops? Im doing my research and thinking about new ways this could be done, but im sure alot of you have a bit more experience in this area.

Please let me know of existing solutions or new ways that this could be implemented in.

Thanks alot
