Ok. I found this little information. Maybe some of you are interessted too.

A little explanation:
Proxies are a piece of software between your client (browser) and the server (from where you get the stream). The browser normaly sends your adress to the server. With that the server knows where you reside. With a proxie your browser sends all his requests to the proxy and the proxy handles all those requests for you. That means that for the server it doesn't sees yor adress (browsers adress). The proxy sends your requests as it's owns to the server. The server now is only able to see and therefore validate the proxies' adress. So if the proxie matches the requirements of the server (american adress yes/no) you can watch the stream even if you life outside america.
But since using a Proxy always means lowering the bandwidth (because proxies open to the public are often not financed by companies they have not the hardware to route a lot of data) i can't imagine that this will really provide a good stream. But i will give it a try.
Now Hotspotshield goes a little different way. This VPN tunnel thing is simplistic really nothing else then a proxie i explained above. So for my intention (to get another Adress) it will work. But Hotspotshield also advertises security for your data through their VPN tunnel. Now i would be a little carful with this. If you use this service all your data (eMail, Passwords) will be routed through Hotspotshield gateway. the route between your computer and the gateway is secure (crypted). but after the gateway your data must somehow reach the desired destination. and that destination (your eMail server for instance) needs your data decrypted. so Hotspotshield will decrypt your data after their gateway and send it to your email server unprotected.
That means two things:
1.) your data will be send through the public network unprotected anyway
2.) Hotspotshield's gateway is a centralized point where all your data can be read by the operator of Hotspotshield. I don't know nothing about them so i would be catious here.
I must admit i spend only a few mins to read about Hotspotshield. So i don't know everybit of how this whole thing works. I just wanted you to warn you if you are going to use this service for more then hiding your adress be careful with it and be sure about what you are doing.
Anyway if someone here decides to stream the game also i would highly appreciate it
