I believe it is quite clear from googles terms and conditions that this is not accepted white hat optimizations. From a user point of view it can only be seen as spam as they would never have clicked the link, had they known it had to be payed for. The customer is surely right that it is possible, and maybe also right that everyone is doing it, but nothing in Googles terms and conditions would stop them from banning the site if they felt like it. Show them Googles T&C and ask if they still insist on having a cloaked site. There is no way you can give a guarantee that their site will not be banned, and they will have to take this risk into their considerations.
