A bitcoin ATM is not possible without user identification, because if you understand the economy in a decentralised consensus and how the current fiat flows, you'll realize that this is how black money gets converted to white. In which case this becomes an 'exchange' in real sense.
So I highly doubt there'd be any ATMs in India.
Coming back to topic, than the arguments here, I think this primarily sums it up. Specially in India, all these factors matter more than in other countries, but I still wonder arguing with the same reasons how do other countries allow them. So I highly doubt there'd be any ATMs in India.
A right question with many legal questions hovering around it. Let me know if you want an Legal Opinion
