+[o] Oleg's idea about participant on_reply
+    http://groups.google.com/group/openwferu-users/browse_thread/thread/2e6a95708c10847b

+[o] receiver / local participant : reply/forward/proceed/... mess : fix
+[o] storage participant : accept string for fei

+[o] fei : place engine id in fei.to_storage_id (and back)
