While I'm sure the technology needed to stream content is improving, all I have to say is:
"Who the heck, other than someone stuck in an airport somewhere, wants to watch the Super Bowl in low to medium resolution on a tiny screen when you might have an incredible home theater rig to watch the live, HD broadcast on?"
Yeah, I get it, that experiments like these push the technology forward enabling greater and greater access to higher and higher resolution content... eventually.
But for now, I can't abide streamed video content. Over my 20 Mbps connection, streamed content can't come close to matching even DVD content.
I just don't understand spending a serious chunk of change on a system (and, granted, my system is, at best, mid-fi, but, still, for a guy of my means, it's a serious investment) and then feeding it a crappy signal. It's kinda like getting all dressed up for a big dinner date with your significant other and going to Burger King or some other fast food restaurant.
