Our company has put out a web product that customers will be able to use on their own servers.. but there are a couple pre-defined spaces that I need to place some text that will update on all their sites whenever I change it (they will pull this text from our server.)

Can this be done with the same code used to display banners? What is the code? I may be able to get away with using graphics instead of text, but I don't even know the code for that..

Any help would be greatly appreciated!
