Watching Rugby Online

I'm a rugby fanatic, and I'm looking to watch it, at least online. I've found a couple sites (Rugbyzone, Setanta, etc.) who offer video but at a price. Then I found this gem Live Fox Sports Rugby and I didn't know a couple things about it. I've googled (and googled and googled) this to try and find out more but I can't get really past this one simple website, which is making me more cautious about doing anything concerning it. So, to you .Org members, I have two questions.

1. Does this work in America?
2. What sorta reviews does this have?
3. Would it be advisable to install any software from here to watch rugby?
