Yep, scam.
The only value I can think of, is it would put the streams in one program (as opposed to googling, or using lyngsats links), hardly worth 100 bucks (there are lots that do this free), and chances are once the stream urls changed for the streams (read: once the stream providers find out people are using an app that they don't profit from (no ad revenue) and is sucking their bandwidth up), they'll change the url, breaking the application, and although some may offer updates, most stream providers will simply use another method that the offending application can't deal with (such as serving the stream through flash or proprietary player), either way the customer gets screwed.
