+* Documentation - document the REST API and the setup process
+* Increase test coverage - the API is currently not tested
+* Better monitoring tools - analyze the data streams, monitor for errors, etc.
+* Archive functionality - allow to store all data to an archive for further
+  processing or analysis at a later time
