I'm not buying, at least as for now. I will try the free package lasting for 9-10 days, I guess, and during that period will compare the delay of stream, lagging, picture quality etc. between internet feeds, streams and NBALP.
Last year, when I had a chance to follow the same game from 3 different ways (when a game was televised by our national broadcaster) - TV, internet links, NBALP, the time difference,delay between streams was most in NBALP, which was broadcasting the game nearly 40-45 seconds after the actual gametime flow. That made me uncomfortable with LP.
There are various websites that offer links to watch games and I was able to watch some Jazz games in HD. This year, I expect better performance and variety. As for the IP, DNS problems, I use a program to get a temporary IP adress from USA -generally from Chicago area-, I can help you on this, if you want to use P2P programs like Sopcast etc.
