India has one of the better ccTLD's (1.Viewing)

By open up I mean the restriction for selling them at market places, the value of those domains would skyrocket.

.IN used to be open, it's getting worse and worse with their KYC requirements. They are trying to force registrars to sign new contracts and a number of registrars have stopped selling .IN domains or at least considered it. It's likely going to get worse before it gets better.

Thanks for your insights.

.in domains have strong branding potential, and easing sales limits could raise their value.
