Re: The ultimate ad-blocker
"So yeah, the visible viewport would not show ads to you; but this concept fails to address the bandwidth, performance, and security issues that the current generation of ads has foisted on us."
Security issues wouldn't be a factor unless you have an exploitable /dev/null. Bandwidth, set a maximum size - accept the first K or so and then break the connection. If the advertising agency has any wit they'll count that as the full advert sent and bill the client accordingly.
