+# Design
+
+Allow for a session based design - data needs to be collected per block 
+and immediatly made available. Minimal or no internal state keeping!
+
+- first collect names and ids of message_types and senders (stored in session)
+- register listeners in session
+- listeners inject captured data with signals
+
+
+- keep naming "classic" ??? ... above session is a tracker with a sender with sensors
