"Game changing" is thrown around way too frequently these days, but man, this thing just might be. The Livepack is being described as "a satellite television truck in a backpack" by creator Livestream, and for all intents and purposes, it is. Put simply (or as simply as possible), the pack includes everything one would need to stream "HD quality" footage: encoding hardware, a Firewire cable and the real kicker, a built-in wireless connection with six load-balanced 3G modems over three carriers (AT&T, Verizon Wireless and Sprint if you have to know). Users simply provide their own camcorder, mash a button when it's show time, and out goes the signal. The Livepack can currently be rented for $2,500 per month (includes 30 hours of streaming) or $1,500 per month if you commit to a year-long agreement. So, who's up for showing the world their high school prom live in HD? Demo vid is after the break.
