This debate is getting really thin. It seems we all live in a world where 5-6% of users are on IE 6. Yet we give this percentage huge leverage in our development efforts. Arguments that "clients are using it on sites/services they pay for" are misguided. What everyone should be doing is developing against forward looking APIs (HTML 5) and shimming to the non-compliant browsers. And for IE 6 in particular we should develop UX that let's the user know they are missing out, with instructions on how to update. It's not about ignoring them or leaving them in the dark - it's about educating them on what they are missing. Just the security aspects alone could prompt a user to update.
For the corporations who still image the desktops and/or make IE 6 standard: stop buying vendor products that require it. Easier said than done I know. But if serious IT groups were serious about saving money and/or standards they'd simply admit that IE 6 is costing them more than an update to their "standard browser".
