Well, for me, I love developing for iOS. The development tools are just awesome. They've made real effort to make it simple and fun (compare that with other Environments).
Regarding making money, I do make some money from the apps (not enough to replace my day job), but that's the case for any other thing you pick up. There will be competition everywhere.
But Live streaming is also available on Youtube: http://www.youtube.com/user/olympic .Why are you not using that? Isn't it accessible in US?
