Could you recommend based on your experience a PHP/MySQL-based admin interface for managing your website ads? In order to be really useful, such application should have:

-basic CRM functionality to track who is providing the ads

-multilingual multi country support: have the ability to specify for the same ad, different versions for multiple languages/countries

-predefined ad formats (google Ads, flash ads...) and sizes with corresponding PHP helpers so as to insert in the HTML code the necessary markup to properly integrate the ad.

Ideally if that application could be desgined for Zend Framework that would be awesome (but I think I'm dreaming at this point).
