This NASL season, there will be a centralized place to watch all NASL matches: http://www.ustream.tv/nasllive1 The details are right here --> http://www.nasl.com/index.php?id=3&newsid=1855 And with the image found there, they make it look like a networked deal, which is cool!
We can only hope and pray for better quality feeds this time around so it will actually be worth watching.
