Do we want to generate it by hand, or automatically?

The former will take some time to be completed, but will probably be correct 
(although maybe not complete).

The latter will be more difficult to achieve as there's no simple way to 
make the distinction between protoA-over-protoA and concatenation of various 
protoA messages in a lower-layer PDU. Consider for example IP over IP and 
concatenated X11 operations. The protocol hierarchy stats are still confused 
when processing X11 data :)

Maybe we could add a mechanism in Ethereal to distinguish between the 
"tunnelling" and "aggregation" cases. Or maybe not.

Best regards,

Olivier
