Matt Pope : One of the more interesting aspects of GWS is that it is that the web services provider is the Groove client itself; web services from the desktop. The API is callable from both local and remote programs. In the former case, we have a local SOAP server running on the same machine as Groove. Radio is the only program I've used that employs a similar model (local http server).
Hugh Pyle : Take a local application which can subscribe to RSS feeds and which can make SOAP calls. Ping the local Groove installation via SOAP when there's new news. Punt the articles into a Groove space you're sharing with friends and colleagues. Bing! Any takers?
