Retargeting and Remarketing data Standardization

What do you all think about standardizing retargeting and remarketing data so smaller networks can join and create a doubleclick style retargeting network without any business mergers? This would be similar to our http://dadf.org/ or Google/Rubicon RTB. Cookie data doesn't need to be collected under a specific domain. We could collect it under disparate domains then use the standard protocol to aggregate it, beating the Doubleclick, Admeld model.
