Netskrt - ISP-colo CDN

Anyone out there using Netskrt CDN?  I mean, installed in your network for content delivery to your customers.  I understand Netskrt provides caching for some well known online video streaming services... just wondering if there are any network operators that have worked with Netskrt and deployed their caching servers in your networks and what have you thought about it?  What Internet uplink savings are you seeing?
