I'm just thinking about how this would work if I were to set something
up using existing tools. I would probably do something like this:

On the remote machine:
        tcpdump -n -w - | ncat -l

On the local machine (running Nping):
        ncat remote | tcpdump -r -

I think it would be nice to have the results in a pcap or other standard
format, so that they can easily be used by other tools. And I know that
pcap has a timestamp for each packet.
