Perhaps we're thinking of different things? This sort of functionality
certainly has no place inside libpam. However, I can't see why you
couldn't have a PAM module that tells the appropriate local/firewall
daemon that something strange is happenning on a connection from a.b.c.d
and wouldn't it be great if it stopped for some amount of time.

Are you thinking that embedding the daemon inside a module is a bad
idea? I completely agree with that.
