Just saw this paper in the last TOC. I have only read the abstract and not perusing it, but perhaps my be interesting: The Convergence-Guaranteed Random Walk and Its Applications in Peer-to-Peer Networks http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/trans/tc/&toc=comp/trans/tc/5555/01/t1toc.xml&DOI=10.1109/TC.2007.70837
