+// This is a purely experimental module and is not yet generally useful.
+
+// The eventual goal is to provide a json backend to fetch content and fill the current page.
+// The page will be filled in on the frontend using javascript.
+// At the present time this page is based on "network", but the hope is to extend to serving
+// any content (wall, community, search, etc.).
+// All search parameters, etc. will be managed in javascript and sent as request params.
+// Security will be managed on the backend.
+// There is no "pagination query", but we will manage the "current page" on the client
+// and provide a link to fetch the next page - until there are no pages left to fetch.
+
+// With the exception of complex tag and text searches, this prototype is incredibly 
+// fast - e.g. one or two milliseconds to fetch parent items for the current content, 
+// and 10-20 milliseconds to fetch all the child items.
