Java around the world

I am renting a CSS server and would like to plog in the stats to my webpage and maybe create a webservice or class library in .NET for the community. I know it is posible but need to find the source, gamemonitor.com, xfire, and others display stats from a server. I want to be able to return the stats from a server in XML format so anyone can parse it. I think this would be a great option for many clans and gaming groups. I also want it to be free for me and free for them.
