Zynga and a few other companies are already opperating in a slightly grey area. poker for example, you play with chips that are essentially free, but you can pay for more. I don't know why FB would want to be involved either directly or un-directly. There is potential for users to loose lots of money. They will blame FB not Zynga. Most users won't realise the 'app' isn't part of Facebook.
