Zach lives! (Miki says, "Hi!")

You raise an excellent point about re-packaging packets, and you and
Nate have helped me to re-think what I actually need in terms of
timing precision.

pcap, huh?  I like it.  I feel foolish because I've used tcpdump and
wireshark for other projects.  The freeBSD's GA311 NIC supports
promiscuous mode.  I'll figure out the rest the hard way.

Thanks,
