This service is designed to provide effortless name to key and the inverse conversions. It does so by utilizing web services that are readily available and acts as a proxy that strips things down to where they are easily usable within LSL (or any other application). It is hosted on Google's AppEngine, which means that it should easily scale with most demands placed on it.
