+ * inherit from this and also implement the appropriate interface.
+ * It provides asynchronous functionality for sending requests to the filetokens
+ * server and processing the responses.
+ * Some methods are const so they can be called by the cert apps client, whose
+ * interface contains several const methods.  These methods need to create
+ * internal buffers, and this leads to iRequestDataBuf and iRequestPtr being
+ * mutable.
