Hoi,
I blogged about the Indic Online Keyboard;
http://ultimategerardm.blogspot.com/2010/06/linux-provides-input-methods-fo…
supports many Indic scripts. I do not know if you know it and I do not
know its quality.
What I do know is that it is open source and free. Is someone interested in
looking into this tool and write a review. I am quite happy to host you as a
guest blogger. I am also happy to blog and refer to another blog.
Thanks,
GerardM
