Agreed,
Heres my situatuation: I need to create rules on the fly for 
(potentially) up to 4000 users. What I need is a way to delete *all* the 
rules for a given ip address without knowing the full contents of the 
rule (only the ip); as you might have guessed, I'm doing this 
programatically.

My current solution is to have one chain for each associated IP. Is 
there a better solution to this problem?

As for memory...I can have as much as I need, if anyone knows how much 
that would be. :)
