I agree with the OpenWRT idea.  It would take little effort to get a
router upand running.  You could even do some magic to bridge the two

No magic software would be required and once that is working and passing
traffic, I would suggest doing something simple like:

tcpdump -i eth0.0 -w imspyingonyou.cap -C 10

This will capture all traffic on eth0.0 and write it to a filewith a
maximum size of 10MB.  It will then roll over the filename and create a
new file.  You could then install Samba to allow remote access to the
cap filesand then just open the files up in Wireshark.  Just get the
tcpdump command to execute on boot and you're golden.
