If interested, check out our old (2001) paper about gaining entropy from the network delays 'Collecting randomness from the net' http://citeseer.ist.psu.edu/565210.html or directly: http://www.crysys.hu/publications/files/BencsathV2001cms.pdf abstract: Random data in the work is collected from network time delay measurements and its quality is checked by statistical tests. A special enhancement: the system of collector-servers is proposed and analyzed. boldizsar
