Can you Recommend an Advertising Server Setup?

I'm in the process of setting up a blog network and I realize that I want to have complete centralized control of the advertising on all of the sites.

Some of the requirements would be:

Rotate ads by type [CPC, CPM etc]
Reporting on impressions based on ad unit
Reporting base on URL of page
complex targetting: show ad from Group A to user and if they make another impression show an ad from Group B advertiser

Probably lots of thing that I haven't even thought of yet. Please suggest other things that would be cool to have in an advertising set up like this.

Any suggestions for a script or product or service that can manage this type of setup?

 

www.adspeed.com
But I feeled compelled to advertise my own ad network as well, so
publisher.freedomofads.com
100% revenue share, its like having an adserver FREE
lol

 

Thanks a lot, adspeed.com does look like pretty much exactly what I wanted.

No problem that you plug your own service, but I had trouble figuring out exactly what it was...there doesn't seem to be any detailed info on your site and if I click the banner at the top I go to Cliksor? Which I think is the group that provides contextual "hover-over" ads.

I'm open if you want to explain more how you see this relating to my needs.

Thanks again - rep added for good info,

Jon
