Question: When is the ideal point in time in which should Jool print the trace?
a) As soon as it receives a packet b) Somewhere in the middle of a translation (when?) c) After having translated successfully, right before sending the packet d) After sending the packet The trace is currently being printed during a). I think the answer depends on whether the trace is intended to show all packets, or only the packets that will end up translated successfully.
