Actually, you can, in fact sniff fibre.  Additionally, if you have
physical access anyway, you can be a literal man-in-the-middle, bridging
all traffic and keeping a copy for yourself.

You could probably do something with the tun(4) device.  And there's
probablly some l2tp software in ports/net that would fit your needs (tund,
vtun).  l2tp would have higher latency and overhead then just encrypting
ethernet payloads, but it has the advantage of being already available.

 I worry about my child and the Internet all the time, even though she's
 too young to have logged on yet.  Here's what I worry about.  I worry
 that 10 or 15 years from now, she will come to me and say "Daddy, where
 were you when they took freedom of the press away from the Internet?"
