I wouldn't do it myself, but if you make 2 ip addresses on the same
system with one higher pref and one lower pref, and ran the tarpit (or
at least an information collector) on the the higher pref ip address,
you may get a decent sample on whether or not your idea is going to
interfere with your regular service.  Since both are on the same
system, nothing should ever contact the higher of the 2.
