there is a paper  I published at the 2004 P2P Knowledge Management
Workshop which makes some observations about query routing performance when
a self-organized P2P network assumes states with different clustering
coefficients (with a fixed maximum outdegree -- i.e. routing table size --
The bottom line is that you can "over-cluster", leading to what Duncan
Watts (I think it was him) has dubbed "caveman worlds" -- dense clusters
which are poorly connected to each other, making it difficult to get
messages across at all.
