Channel conflict between ad networks and web publishers

I was prepared to rip into this when I read the title because I just endured the IAB member chant "Ad Networks are not important" for the last 3 days. BUT - the ideas are good - and, having run a publisher with a direct sales force who was concerned about channel conflict, can be implemented.

The only issue is that advertisers may not buy on blind networks (almost all the networks I work with require transparency from me) - so, it may be that the "fence" may be a modified version of the "no guaranteed delivery" and allow networks to dislose (not promote) a publisher's participation without guaranteed delivery to accomplish the same thing.
