An important class of location-based services answers 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 of the type "N
nearest", "within distance X", and "served by".  This document defines 
an Experimental Protocol for the Internet community.


EXPERIMENTAL: This memo defines an Experimental Protocol for the
