I'm interested to know the legality of setting up a online lottery. Probably not something you would want to try in the Philippines or you would be playing Russian Roulette.
You will never receive a global license for a global lottery. In some countries lotteries are illegal, so these people will have to filter/block users from these regions/countries. I doubt if this lottery will operate with a licence, because these things takes a lot of time and money to acquire.
Good luck with your project guys, I hope you follow the legal route. ^smile^
