It is more idealistic then implementable. With a population in the billions and 80% living in rural areas, you can probably imagine the amount of people that are educated beyond an intermediate schools. The possibility of implementation seems extremely limited.

The advantages are definitely there, but I see it getting adopted marginally in the big cities within India first or the likes of Silicon Valley. If it doesn't go far from those cities either from acceptance or convenience, I doubt it'll become popularized period.
