[ What is claimed is:] [21.] A computer system comprising:a processor;a memory operatively coupled to the processor; anddistance determining logic which executes in the processor from the memory and which, when executed by the processor, causes the computer to determine relative distances between the computer system and at least one other node through a computer network, the distance determining logic comprising:a sending module which is configured to send through the computer network at least two query messages, each of which includes:an expiration parameter which specifies an expiration condition for the query message; anda data body which includes data specifying the expiration condition of the query message as specified in the expiration parameter of the query message; anda receiving module which is operatively coupled to the sending module and which is configured to receive, from a recipient one of the other nodes, a query response message which includes data specifying a quickest expiration of at least one received ones of the query messages which are received by the recipient node, wherein the quickest expiration is determined according to the respective expiration conditions of the received query messages as specified in the data body of the received query messages; wherein the quickest expiration relates to the relative distance.
