hi all, thanks for sending the links to relevant sources as well as describing the internal work flow for me. I was able to get the necessary implementation details from that as well as a way to integrate XWatch with different web 2.0 services. I will put the development procedure in the GSoc project proposal. I will give my gratitude for that. thanks, regards, suramya -- Suramya Rathnayake Computer Science and Engineering University of Moratuwa http://suramya-rathnayake.blogspot.com/
