Sounds like a good idea to me. There is the opportunity in
restrpc/Server.php to convert the response into the required output format
so I think this will work.

Sounds good to me. There is code in the jsonrpc binding for the conversion
into JSON. In SCA_ServiceWrapperJson.php you'll find

            // convert the reponse from the message call into something
            // that can be copied  into a JSON result string by the
            // JSON Server
            if ( $return == null ) {
                $response_object = "null";
            } else if ( is_object($return) ) {
                $response_object = $this->json_das->encode($return);
            } else if ( is_array($return) ) {
                throw new SCA_RuntimeException("Return from method
$method_name of type array found. " .
                "Return types must be either primitives or SDOs");
            } else {
                $response_object = json_encode($return);
Which checks the response type and does the appropriate conversion.

The json das must be set up based on the the schema that describes the types
in the service interface if you are expecting json to be passed into the
service. In your case you are only talking about encoding return types so
you can get away without doing this I think. If you look at the constructor
for the SCA_ServiceWrapperJson you can see the das being created.

Would be great to have this contributed back into CVS so thanks for the
