I'd say that you could do something with the recent match extension / 
target.  This would allow you to do some things in conjunction to 
whether or not a given source ip address in in a given recent list (you 
can have multiple) or not in a (user) specified amount of time.

You would end up checking a recent list to see if the given source 
qualifies to alter state or not.
