Customize ArcWeb Explorer & Pay For It

When I previously posted about the ArcWeb Explorer (AWX) JavaScript API, there was no credit cost for embeding AWX in a custom webpage. This seemed like quite a deal, since you could hook up almost all of the ArcWeb Services. I wondered how long this free-ride would last. Well the answer is "Not long". You must now register your webpage with ArcWeb Services and recieve a AWX API key for custom implementations. There is nothing explicitly dealing with Public Services users on the AWX QuickStart Page or on the AWX registration page. So I don't know what level of access Public Service users get.
