Hi Russell,

Reading between the lines, it sounds to me like they are looking for 
something along the lines of data loss prevention (DLP) software. I'm 
not aware of any Free Software solutions for this, although I must 
confess I've never looked for it specifically.

Other options might be netflow/sflow, or iptables accounting.  For the 
former, try ntop; the latter: Shorewall.
