<snip what you already gathered> you could add, FOSS movements on enabling Indian language support in FOSS. An incomplete timeline - http://indlinux.org/wiki/index.php/IndLinuxSaga (focus more on activities under Indlinux group), , lot more has happened since 2007 that still needs to be documented.
Then what should not be missed is the grooming of LUGs and other groups, the activities they brought in, events they organized. Every event helped spawn more activities, people. Some venues were the hotbeds for many activities be it places like IIT* , JNU, Sarai, SICSR or the favourite meeting and eating joints of Luggers.
Thanks Karunakar for the updates. I see a lot of the contributions to FOSS in India have happened in the languages domain.
An article may not do full justice, what is needed is a book on FOSS in India, may collaboratively written as wikibook, if all agree to disagree and keep a lid on the flames!!
Let me do this first, then will create a public repo and see if there is more interest in maintaining it.
The key would be to keep it updated. This got started off well, but lost steam eventually
