Walmart’s Vudu movie streaming service is ready to pipe movies directly to your iPad. But don’t look for the traditional iOS app. There isn’t one. Vudu is streaming movies over a web app, which doesn’t force Walmart to share revenue with Apple.Vudu is skirting Apple’s new terms of service that requires sharing revenue. Much like Amazon’s new Kindle Cloud Reader, Vudu can offer all the functionality of a streaming vide app through the magic of Apple’s HTTP Live Streaming (HLS) without dealing with the App Store and its approval police or revenue tax collectors.
