In my humble opinion, Internet classes are the best answer to 2 classic problems: the lack of classrooms and books. The Internet is one big library that everyone can use. Also, any room can be a classroom as long as a computer that's online is present. It does away with the need to build more classrooms, the need to print more books, and the need to suspend classes due to floods, since classes can be held practically anywhere.
The bottleneck here is principally infrastructure. In a country where we can't even put one phone in every home, internet access is an even bigger obstacle. In a country where the last attempt at a countrywide broadband project ended up in controversy, the chances of such an infrastructure going up is even thinner. But I sincerely believe it's preferable to building additional classrooms--there is only so much land to go around, and weather is always a concern.
