        call me old skool...  VI works a treat and I'm told there
        is this thing called emacs ... but i remain dubious.

        if all you have is a hammer...
        folks need better tools.

        which is their choice.  please show me the mandate for accepting
        routes/packets from any/everywhere?

        me, i'd want the option to "block 192.0.2.0/24 as long as it
        is announced by AS 0 and the whois data points to RIAA as the
        registered contact" e.g. not just a temporal block.

        or - if traffic from 192.0.2.80 increases more than 65% in a 150
        second interval, block the IP for 27 minutes.

        or - allow any/all traffic from 192.0.2.42 - regardless of the
        blocking on 192.0.2.0/24

        the mind boggles.

        such is the course of human nature.
