Hi this is Sreenath H B, Microsoft Student Ambassador for RNSIT, Bangalore. I am part of a large community of .NET Enthusiasts from India, like Reza, Aswin who have posted here early. We have many portals which list us, and each state in India has its own way of managing the activities.
For example, my state, Karnataka alone has around 60+ champs and 12 ambassadors. So you all can imagine the magnitude of this program in India. (India has 29 states)
We have a lot of activity and constantly keep in touch with each other.
Check this list of student ambassadors in India: http://www.microsoft.com/india/msdn/academia/Ambassadors.aspx which is by no means complete due to the immense diversity we have here.
And yes this is getting to be a very long thread, hope someone does read my post!
