Online "Operating System"

I came to know abt this Online "Operating System" from my friend. There are many sites that provide you an acct similar in the way of email acct to login and have your own "Online Operating System". Get the sites that provide this facility by googling for the title of this blog and Enjoy:)
This was my idea in 2004. Now, there are many sites implemented this :)

EDUSAT

EDUSAT - A DEDICATED SATELLITE FOR EDUCATION - is the project done with ISRO, MHRD, IGNOU and State Departments of Education. Nice Project. Uses the space technology to share the knowledge. Our Beloved President Kalam made a quote "Democratization of Knowledge". Nice Wording - I liked it :)
