I registered for this last year and it was pretty sweet, and free I just an email saying that VIP registration is almost full. With VIP access, also free, you don't have to wait in lines online to watch the games. Last year I had the regular access and had to wait sometimes for ~10min. So, go to the link below and sign up. http://www.ncaasports.com/mmod I think you get to watch all the games from the first 3 rounds live online and after that you get recaps and highlights all the way through the finals.
I did the same... big fan of it because its the only way I can watch the games at work. Last year they covered practically every game... only one black out that I remember.
I did this last year and it works fantastic. Except where I work now has a tv in the next office and voila...no need for on-demand. I'll probably still keep it on my desktop until the last minutes of an upset. I think I'll go down to Green Valley Ranch and drop a ten on every 11th seed. woot upsets!!!
I think one of the UT games was blacked out for me last year. I was in class or something and wasn't able to watch it.
