Reverse geocoding

[JasonZou]

Hi,
VEGeocoder only has addressToLocations method, but no locationToAddress method. I found a geocoder on esri sample server 1 (http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Locators/ESRI_Geocode_USA/GeocodeServer). But I am concerned using a service on a sample server since it can be removed at any time. Is there any public geocoder out there that can be used for reverse geocoding service freely?

Thanks in advance.

I found a world geocoder published on ArcGIS Online: http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer. But when I go to that page, I got Error: Services Directory has been disabled. However, if I submit a request like this: http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/find?text=380+New+York+Street%2C+..., I can get the result. Is there any limitation for using the service?
