Sure it would be nice to have it, just like amazon streaming. The more choices the better.
But I've always had to play musical devices with Vudu. Their device limit used to be five(which was terrible), but a few months ago they increased it to eight(which is a little better but still not good). But that still doesn't come anywhere close to allowing me to stream to all my Vudu capable devices without having to remove a device to add the one I want to stream Vudu content to.
