I think in GBS I have seen them teaching computer classes and one channel on 'digital tv' was about education. I don't necessarily think they are competitors as of now but serve as an example in the shift of how we view education.
Educational DVD's is a great idea in my opinion.Think about selling CPA lectures and walkthroughs. But education is no easy task. The most important thing to consider here is background of viewers. Different background exposure leads to different levels of comprehension. But this is a matter you can sort out.
You can also consider selling the items in native language.That would be revolutionary! I am yet to see an english - Kenyan(no need to name tribes) home learning dvd. Imagine a group like househelps,they can gain tremendously from the free time they have. Watchmen listening to educational material which can be downloaded just like ringtones.And that's just the lower end of the market.
Curiosity is the most important thing to inspire in a student.It becomes a fire in them that keeps them going and going. To engage I would suggest using symbols and examples that they can relate to. Communication is about use of and sharing common references.
Don't worry about funding.Worry about the content.If you have quality content,people will chase you with their money.
Uncertainty is certain.Let go
