Is working from home a possibility for the tens of millions of developers and call center workers? How's India's internet access at homes? I lived in S. India about a decade ago, and the internet was okay at the various IT offices, but it seemed a lot of office workers used their work PCs for a lot of personal business like banking and media (i.e. after hours), and I assumed this was because access was poor in home residences. But maybe it has improved in the last decade.
