It works in as much as I get the packets through.  I don't have the full 
processing written yet, as there didn't seem to be much point investing 
time in that until the 'foundations' are in place.

In the end, this change is pretty small but it's very difficult (if not 
impossible) to cover all the different playback scenarios without being 
able to pass this metadata through the chain.  It certainly makes life 
*much* easier for the calling application if all packets follow the same
