I would like to do some custom processing on save, with some magic features kind of like how created and updated fields work in DMZ. How might I extend DMZ to allow me such an ability, if possible?[/quote]

Form Validation is fine for this. What you would want to do is make a custom rule for IP like this:

Code:

function _insert_ip_on_new($field) {
    if(empty($this->{$field})) {
        $this->{$field} = ... // get IP address
    }
}

Then add that rule to your IP column, first if you can. You can still process other rules after, if necessary (like unique).
