I use a firefor add-on[1], which works for the Quantcast banners (adds a "I refuse" button), but would definitely like something that works equally well for all websites, or that websites fix it themselves. Maybe even better, if they could simply follow the DNT flag, or not track their users in the first place. I worry that accepting cookies once, for one of these sites, will lead them to try and de-anonymize you, maybe even across private browsing windows, or different sessions. If you give them the right to basically fingerprint you, be assured that they will abuse it.
