I think the Browser could just send a header specifying the types of Cookies it accepts, configurable by the user. One might come up with a few of categories of cookies, and there is already the Do-Not-Track header. The site then doesn't have to store the preferences in a Cookie. The problem here is that some Browser manufacturers might just set default consent (it really should be asked of the user once a new profile is created and changed later, with a per-site override).
