Per Nick Doty's request, I would like to submit TRUSTe's new integrated DNT ad tag solution for discussion / feedback.
The concept is a 'smart' ad tag that is capable of acknowledging a user's DNT header and, if DNT is set:
1) display an alternate state icon with DNT acknowledgment messaging
2) auto set opt-out cookies for ad nets in that particular ad chain
The primary advantage of this solution is leveraging the visibility / transparency of the ad tag to promote DNT as an interim solution until DNT gains widespread adoption.
See here for a more detailed description -

See here for a live demo (ad icon will only appear altered if DNT header is set; interstitial will acknowledge DNT status either way) -
