Well, along these lines WordPress, the blog software that I use,
prevents comment spam by making sure that users with the same IP can't
post more often than every 30 seconds. This makes spambots useless and
expensive to run.
Same can be applied to web application protection, i.e. a single IP
cannot make more than N hits/second or something of that sort.
Of course, this won't work for people who don't have a unique IP, i.e.
people behind routers and firewalls.
