Ask HN: How can I get this working?

Hi guys, I am developing an text-to-web advertising platform and I am stuck at a point. Short description of how it works: Any one can text a 140 character message to a short code, and have it displayed on any website that is on the network of the advertising platform. My Problem: How do I display the text ad on the websites that are on the platform? Iframes? Flash?

These are my reasons for creating this platform. 1. This product is made with the local market in mind (Nigeria, West Africa), I doubt if this would be a hit in the first world. 2. Due to lack of a reliable payment gateway for local users here in Nigeria, I decided to use premium sms (short code). Once an advertiser texts an ad to the shortcode, his prepaid credit is debited, his ad appears on the target website of his choice and the revenue is shared between the ad platform, the shortcode provider and the website owner. 3. Google adsense or adwords isnt too attractive here in Nigeria because of the hassles of getting paid by google another case of reoccurring online payment gateway issues. If you have ever implemented something like this, I would really like to have some tips from you. Disclosure: this has been submitted before, but I didn't really glean much for the few responses gotten. Thanks
