The tool in question may not even exist yet. There is no preset
definition of how it has to work. Perhaps it can be evolved enough
to where it only triggers when an exploit is attempted, rather
than just on a TCP connection.

I can take all the proper security precautions and it doesn't stop
third party network A from being exploited and later used to attack
me. The point of this is that it will help identify a specific host
which is scanning many blocks belonging to many different networks.
If they hit several landmines in my network, I might be concerned.
If they hit landmines in my network and 6 others to which I have no
affiliation, the net as a whole might want to know about it.

I don't think anyone said this was intended to take the place of
security on their own networks. But I don't see how that aspect
makes this a bad tool on its own either way.
