I was successfully able to watch the Summer Olympics last year using a VPN in this manner. Actually ended up watching the whole thing via the BBC -- it was oddly enjoyable to listen to the British commentators remark about the Yanks as if we are a race of athletically superior, somewhat lovable, giant children that are obviously in every other way doofuses :) .
The solution as proposed does not work from the USA for NFL Season Pass. I've tried, very hard, to find a way to make it work. (I cleared cookies, caches, changed the clock on my computer, deleted an installed a browser for the sole purpose of watching these games, etc. etc., to no avail.)
But every time, the NFL can somehow, someway, sniff out that I am a US user, and directs me to the page saying to sign up through your local cable provider. I've never owned a TV or subscribed to cable, so... grrrr.
Happily, Aereo, which last season was blurry, blotchy, and somewhat inferior to going to the local bar / friends', is this year very, very good. I set up the NFL games on CBS and NBC yesterday to record. They recorded, and I watched them from a giant Dell screen I have set up for the purpose. We also watch our Netflix and Hulu stuff on the same screen.
They do have a tough time with games that go over the scheduled time, like last night's Seahawks-49ers game. If you see that that is going to happen you have to go to the next show, and the next, next show, and click "record". So that even though you have no intention of watching local news at 11, Aereo is recording the correct station at the correct time.
For a non-TV, occasional sports fan who does not need a whole bunch of bells and whistles, Aereo is a fine solution.
(And, no, I have no professional, personal or other affiliation with Aereo other than the $10 a month they nick me for the service.)
