Yes, I have written the paper, and have developed the code.

I just joint http://english.sina.com/ (Chinese biggest ICP) the end of last year for this project, and the final target is to try to use Google.com like cluster to control and reduce the storage cost as the Mail, VOD, and P2P fileshare eat tooooooo much disk space. > > Eric > > -- yf-263 Unix-driver.org
