> Currently, there's no way to get the gadget meta data without implementing a 
> full container that uses the core java libraries directly. To rectify this 
> situation, we should introduce a JsonRpcServlet class that will take requests 
> in the form:
> var request = {
>   "requestContext": {
>     "language": "en",
>     "country": "US",
>     .. other per-request fields...    
>   },
>   "gadgets": [ // index should be module id based
>     {"specUrl": "url-of-gadget-spec.xml", "userPrefs": 
> {"up_name":"up_value"}},
>     ...more gadgets...
>   ]
> };
> and responds with:
> var response = {
>   "libs": ["setprefs", "analytics"],
>   "gadgets": [ // guaranteed to be the same order as inputs.
>      {"specUrl":"same-as-input", 
>        "prefSpec": {"up_name":{"display":"Localized, user-friendly name for 
> the pref", "type:"string", "default":"", "value":"same-as-input, or 
> default"}},
>        "contentType":"url, iframe, or caja",
>        "content":"iframe url,  url for type=url gadgets, or cajoled content",
>        "token":"gadget token, produced by a GadgetSigner implementation",
>      },
>     ...more gadgets...
>    ]
> };
> This RPC mechanism should be designed in such a way that it can easily be 
> used as a reference mechanism for anyone that wants to build an rpc system 
> using shindig using alternative rpc mechanisms (SOAP, XML-RPC, various 
> proprietary solutions).
