Not completely useless... with a sniffed MAC, there's a good chance I
can investigate a little and determine whether it is internal, and if it
is, what switchport it's on (and therefore, in my case, which room it is
in).  Even determining the traffic is coming from outside my network is
a helpful bit of knowledge.
