I agree with mwzd.
Aside from the other potential 'meanings' for .IN, India along with international companies entering India will support the future of .IN.
Invest wisely and Be Patient.
India is the 7th biggest continent in the world and many MNC's prefer india to other asian countries as Indian's have a good neutral english accent unlike their neighboring countries. india will top population soon.
Right now i think only 0.00001 of indian's know what domain business is.they are also becoming more and more tech savvy.
