IF GS is planning to acquire VLNT for these patents then they may have a speculative purpose for 'using' these patents, possibly a r/m with a pre-existing telecom in order to provide streaming video (IPTV) is one scenario .This is my best guess since it's an emerging market AND it's going to compete with cable and satellite providers which = major $$.
Since streaming video is yet another major revenue producer and upcoming popular service provided by ISP's I could understand why a telecom (or ISP) would be interested in leveraging these patents as well as new video technology compression methods.
