An important class of location-based services answer the question "What instances of this service are closest to me?" Examples include finding restaurants, gas stations, stores, automated teller machines, wireless access points (hot spots) or parking spaces. Currently, the Location-to-Service Translation (LoST) protocol only supports mapping locations to a single service based on service regions. This document describes an extension that allows queries "N nearest" and "within distance X".
