The opportunity to provide a uniform script to all Indian languages was lost way back at Independence time. The need of the hour is nurturing of Indian languages among Indians, and this could have been done a little more easily if all Indian languages switched to the Devanagri script. After all, most Indian languages use the Devanagri in some modified form. Bengali for example had its type designed by Englishmen from the Devanagri. Romanization of Indian languages may be a good idea, provided it is done for all languages and a similar phonetic form is adopted. But then you are throwing away a script form of thousands of years. Very soon India will assume its rightful place as an economic superpower, and it cannot do so unless it asserts its culture as well. I say stick with the Devanagri and expand it all Indian langauges.
