Ads/banner server script or something

Hi all!

As everybody know, we can put google adsense and all that stuff on our dolphin site. Then we dont have to take care for any other things.

But, i got a question now from a company who wants to make advertisement on my site and i have to track all this.

Now i wanted to ask you which server script you are using for delivering and tracking ads/banners.

Im playing around with OpenX http://www.openx.org/.

Maybe some of you got some other links or tools...

Hope you got what i mean ;)
