This is great for the industry I work in.
Think of it this way....we would not have Skype and the likes without the transition from Dial-Up to high speed cable or DSL. This will allow users to Skype in high definition without bandwidth issues, lag etc.
Not sure how many of you use Teleconferencing (VTC). There are software applications that allow the user to dial in on a bridge (take Tandberg (now part of Cisco) for example). They offer a desktop software that allows the user to dial in on a bridge or far-end Codec. The bridge allows for multiple users to interact in one conference call from different locations (for the non-IT people out there). This type of bandwidth from home will allow desktop users with the software to experience high quality, uninterrupted video conferencing. This is huge in higher education for distant learning, or businesses with salespeople always on the road. I see this fiber broadband having a major impact on telemedicine.
Also, we will have the ability to download a HD movie in under 5 minutes.
As far as why KCK was chosen... I've heard infrastructure, population, influence of JoCo business spenders (on the news Google called this "easy people to work with"), and I-70 corridor.
