Rss display script that will rotate links

I want a little php script that webmasters can place on their website to display RSS feeds from news sites, blogs and whatever else. The main function of the script will be that becuase I will give it away for free I want to be able to rotate 2 different links at a time to my websites at the bottom of the RSS results. I want it to be impossible for the webmaster to remove the links from the script. I want the script to connect to another script on my website where I can log in and plug in the links which will automatically spread them around the network of all the sites that will use my script. I want the script to be simple to install and basic. I want the script to run based on a template which webmaster will be able to edit so it matches his website. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
