I think OP realised that this system wont be that viable in india.
like how many indians actually use bitcoins or know how this system works..
to begin with, it will take time from explaining technology to mass.. and then introducing this system
That itself is not the problem , i think the main problem will be with Bitcoin payment using in taxation problem, as still bitcoin is not legal or still their is not clear picture of where bitcoin is in legal system. So when you start a business using bitcoin as payment system then their will be problem from government and law.
