For those interested in research related to Tamil:
There is a center called 'Resource Center for Indian Language Technology Solution - Tamil' operating under the Computer Science Dept. of Anna University, funded by the central govt. So the scene in Tamil research is not as bad as it seems.
You need one of these fonts (TAB-Anna, TAM_ELANGO_Barathi, TAM_Aniezhai) to view the page.
There are quite a number of projects going on there. And they developed stuff like Tamil OCR, Tamil hand writing recognizer (my project ;-) ), speech synthesizer etc.
