Nick and Roger suggested that we figure out how to communicate to policy people in their own language why we are reluctant to believe DNT will actually accomplish anything productive, and therefore why we are reluctant to endorse it.
I hold a slightly more extreme position: That DNT is actually likely to introduce a regulatory sinkhole that we want no part of. In almost every case, we should be developing end to end cryptographic strategies to dealing with the issue of infrastructure trust and tracking.
We should spend the time to communicate these ideas to the DNT folks. To quote Roger, "the more the policy people think they're solving the problem, the less likely anybody is to solve the problem."
