It's cool that they finally support external hard drives, but it would be even better if 2 DVR's on the same network could share/stream content between each other. So you could have your primary DVR in your main living area that you probably use both tuners for recording non stop, and then maybe one in your or other bedrooms that you record different programming on. Or if you had network storage watch the shows that are saved on that device. It seems like there would be enough bandwidth on a traditional 100mbps network. It was my understanding that an HD signal was only about 15-30 mbps (I'm guessing this is probably 1080i) but even if it was a little higher there is still plenty of bandwidth to go around.
