Ask HN: Free Ad Network with 100% rev-share. Will there be takers?

I plan to build this and I wonder if this is something that bloggers/websites will use.<p>Basically, I have a few websites and I am using Adsense and some other ad networks. I was thinking if I build a complete ad network for my sites, I can earn 100% of ad revenues.<p>Do you think others might think the same as I do?
