tracking-ISSUE-159 (mashing): How do we allow sites that mash-in add-supported content to maintain their own 'trusted third parties'? [Tracking Preference Expression (DNT)]

Raised by: David Singer
On product: Tracking Preference Expression (DNT)

Imagine a site A that is (a) ad-supported and (b) mashes in content from site X that is, in turn, ad-supported.  Say in turn that the user has granted a site-specific exception for X, but not A. When visiting A, X's third parties will not, under today's model, get their DNT:0.

The problem is that it looks, on the face of it, impossible to distinguish iFrames that represent mashed content and that should start a new context, from iFrames that are being used to embed and maybe 'sandbox' ads, and that should not.

Proposal: we punt on this corner case for the first version of the spec.
