I don't seem to have that kind of latency with anything else on the
remote box...  Wouldn't it have to be under some serious load for
tcpdump not to display the packets for >10 seconds?  Admittedly, it's
only a ppro 200, but the load on it is pretty nil.

Seemingly true as far as I can tell.

tcpdump -i any doesn't seem to give me the interface the packet shows up
on.  Is there a way to make it do that?  Didn't see it in the man page. 
I could run a separate tcpdump on each interface if it matters too much.

This appears to be true.  192.168.1.69 is reporting 100% packet loss.
