I have found a good software (well actually a web ware) OPENADS. An open source Advertising program.

well we can easily add different adverts, give them priorities, even google adsense can be added to it. Even Geo targetting Feature is been added lately.

There are two version of Openads currently available:

* Openads 2.0 (aka phpAdsNew) – currently the choice of over 90% of the Openads community, and - serves upto 1 million ads per day
* Openads 2.3 (aka Max Media Manager) – Still under (TEST MODE) the experts' choice for those with more sophisticated needs. - well can serve upto 1 billion ads per day

check it out at : http://demo.openads.org (its the current latest Under Test version)
