On input, it could help paralyse identification of packets type: each protocol
of the same layer level could look and eventually *take* the new packet at the
same time. Also, packets capture feature come to mind. Live net stats...
On output, multicast but also interfaces bridge could take profit of buffer
sharing.
And last but not least, loopback interface. Unix sockets too.

But, sure, you can do that without sharing buffers too, by just duplicating data
data. :-)
