Ads over flash video player

We need to implement javascript library which allows to display ads (banners) over flash video player. How it works: 1. Script creates 'div' element and puts it over flash player. 2. Scripts inserts 'iframe' into 'div' element and renders ads inside iframe from remote server. 3. Script should be compatible with JW, Flow and Kernel Video Player. 4. Script should display ads on Pre-Roll, On Pause and Post-Roll player events. 5. Script should work with embed video players (when you insert the code of player from remote server). If it is possible of course;) 6. Script works correct with IE7+, FF, Opera, Safari, Chrome. That is how it should look like: [login to view URL] ([login to view URL]) It will be great if you have been doing such task before and can show examples. Thanks.
