Actually, I doubt the relative strength of the INR is going to be nearly as much problem as the Indian forex restrictions.
C3K will pull in revenue in INR which will offset its local expenses--salaries, rent, commissions, landing fees, etc.
However, if the bulk of their income is Indian origin, they are going to have a hard time pulling any of that money back in to Canada.
That's what ultimately killed AC's Indian services--it wasn't that they couldn't earn money, it was that they couldn't realize any of the income.
