Lightning

I was wondering if anyone knows the legal issues of online casinos. Specifically I know online gambling is illegal in the us. But since the actual casinos and money and all of that are actually offshore, is it ok to have a casino branded to your sites name, then you host it on your servers, but all the links and actual gaming transactions are done by the real casino themselves??..
I hope this makes sense?
Any input would be greatly appriciated.
