Ad insertion firmware for wifi like Silver Lining Network

I have some wifi hotspots and I would like to seamlessly place ads on all of the pages of the users accessing my free wifi network. [login to view URL] and [login to view URL] have good example of what I need. I also would like it to function with Openx ad server and to work with DDWRT compatible radios. We don't want a banner at the top or side. We are only interested in serving full pages ads and video commercials of local businesses by the amount of time they spend on our network. Just like TV maybe every 15 minutes? How long until it will be complete? ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
