To respond to this 3 weeks later, this sort of dovetails very nicely into an
idea I've been kicking around for a new toolkit (component) built on top of 
libnet, libpcap, and libdnet to do all sorts of high-level low-level stuff...
The idea you're talking about, is along the lines (I think) of an idea I've got
for functionality called "Network Contigency"...  Basically, given situation X, if \
response Y is seen, do Z.  With libnet and libpcap and some callback functions, this \
can be implemented rather elegantly.  I have some other ideas for this component as \
well, when I get some time, I'll throw something  together...
