You might make a posting about Bitcoin in the FSF Tamil Nadu group. You can find their mailing list at
http://fsftn.org/mailing-listBack when I wrote some things on free software they seemed to pick them up pretty well.
If BTC becomes useful for remittance there will be a need for people to sell BTC elsewhere and wire it back as INR.
Hey guys. I'm from India too. There is one way in which it is possible to increase public awareness about bitcoin: techfests conducted by the IITs, NITs, and other engineering colleges. These fests allow individuals from outside (i believe) to hold lectures and workshops - an effective platform to spread knowledge about bitcoins. An added bonus is that college students in top colleges are receptive to new ideas and a great many of them show interest in building startups.
Initially disseminating knowledge in a few techfests like Shaastra (IIT-Madras), Tryst(IIT-Delhi), Daksh (SASTRA University), Techfest 2012-13 (IIT-Bombay), etc.
Any comments/suggestions/ideas?
