One way to go about the international popularization of the symbol is printing and circulating, and another is branding the symbol on keyboards. So once the symbol is passed by the required authorities, we're gonna have the symbol on Indian keyboards-cool eh?
For some unfathomable reason, I'm all excited about the INR getting a symbol! It somehow comes off as very 'Indian', because of the adaptation from the Devanagiri script. A pretty picture, a symbol with a history creating history.
