I have been using WD live Hub for last one year. Last week i used the same to stream educational videos fron Khan academy for my kids. I realised that this could be one of the best uses for showing learning videos on large LCD ( blackboard ) for the kids and for the WD Live Hub.
Is it possible for you to create a small application that can help filter/choose learning videos from Khan Academy library. the application should be able to catalogue and display the content list for easy selection.
