Nor did we.

For a long time the bridge box had an IP for administration, but no
default route, so it couldn't connect to anything outside of the network.

One of the bridges I have is doing traffic shaping. The idea was a
drop-in traffic shaper, didn't require any changes to either side
(although inserting such things soon reveals interesting ARP table
behaviour on some boxes, for which a reboot was the easiest fix in most
cases).

Be curious to see how much data, and how quickly you can store it.
Looking at stuff here, it is relatively easy to store stuff to disk
faster than it crosses the network, but the disk used to log stuff would
fill up fairly fast, so we'd probably only be able to store a few days
worth, and then there is efficient access to it....
