Hey, this is the guy that sent in the lame thought about the controller streaming and battery life. It was awesome that you took the time to destroy me! It was based on the observation that, almost universally, streaming video does terrible things to battery life on portable devices. Watching a movie over wifi, for example, can be tenuous. Instead, playing a non-intensive game locally, such as Angry Birds, can allow for many hours more before the dreaded red light.
Consider an 800x600 image moving across a 600x480 screen. If you have the original image, it requires almost no processing to render this movement (just show a different range), whereas with streaming, you need a full refresh of the image for each frame.
Also, you quickly throw out that bluetooth streaming would be easy, but it seems that this would lead to really terrible video quality at a decent resolution (low bandwidth), apart from the battery issues. Quality will increase as you increase compression, but then you are stuck again needing substantial processing to decompress the video, killing battery life. Do we really want the video equivalent of the tinny speaker on the Wii controller?
These are just some observations and I am not an expert. Which is more efficient depends on the situation, and perhaps both (heavy decompression and app-type downloads) will be available, or a high bandwidth connection to use in bursts.
