+    - server: some stuff to prepare for distributed storage
+        - don't create result records for uploads and downloads.
+            Just create a msg_to_client record.
+        - the scheduler handles file-transfer results specially;
+            it makes a vector of them, then calls a project-supplied function
+            handle_file_xfer_results()
+        - change the interface and implementation of put_file and get_file
+    - client write project sched priority in GUI RPC replies,
+        but not to the state file
