Umm..to be specific, perhaps I should left the word "biggest" away :). In fact,
I just wanted to give *one* example of problems in DHTs. However, there are
*much* more unsolved problems related to DHTs (as we know). For example, please
look (if not already looked):

a) http://www.cs.rice.edu/Conferences/IPTPS02/174.pdf
b) http://iris.lcs.mit.edu/proposal.html
c) http://ciae.cs.uiuc.edu/SRG/summaries/summary-9-4-02.html
