I have started learning about Arduino, buying a number of boards and really enjoy the process. As I look at the Beaglebone, Raspberry Pi, etc, I see the possibility of using this small platform to carry curricula. I have been developing Special Education curricula over the past decade, and have the idea of placing everything I've developed onto a board for a student to use independently. My thought was to have a Linux operating system preloaded with all the curricula, PDFs, html, videos, etc. The student would simply have a plug and play access to all the resources on the board. I would like some feedback from users if the platforms could support this idea. I have the very little knowledge in this area and looking to learn.
If this is feasible I would prototype for beta within 1 month and demo in October.
Re: Pi's ability
It would be a great idea. Backup the SD card and image that to all the other SD cards. Just make sure that they can't play any online games or any of the example pygames. 
There are 10 types of people: those who understand binary and those who don't.
