Do you think that Bangla Word software can show way to type easily Hindi, Oddisi, amese,Marathi and others?

There are many softwares to write Indian languages. There are many similarities among Indian languages, because many of them come from the Devnagari letters. I find the "Bangla Word" Software very useful to write in Bangla. If the software be modified by their creator, it can be used to write Hindi, Marathi, Nepali, Odissi, Punjabi Gurumukhi, Gujrati very easily. Do you think the Indian Government should approach the Bangla Software Group, Bangladesh/London, who are the original patent holder to have a business contract/license signed to modify/develop their "BANGLA WORD" to develop writing software for other various Indian languages?
