1. A cache memory architecture for use in a peer having at least one locally registered peer ID within a peer name space, the peer name space having a first number of peer IDs instantiated therein, the first number of peer IDs having an average spacing therebetween, comprising: a second number N of memory regions for storing peer IDs, each memory region from 1... N storing peer IDs within a range of &plus;/−10 1... N times the average spacing from the at least one locally registered peer ID, each of the memory regions 2... N excluding the peer IDs stored in preceding memory regions 1... N−1; and wherein the number N of memory regions is determined as the log of the first number of peer IDs instantiated in the name space.
