Good news is that 1)Sheraton Rio has ESPN
2)ESPN has exclusive rights to the Trinations
Bad news is that they are showing the match 32 hrs after its being played
Worse news is that even flying from Rio to Buenos Aires won't help as ESPN in Argentina isn't showing it live either.
Appalling news is that ESPN is showing a friendly between Ireland and Scotland live on Saturday -well of itself that's not appalling, but to not then not show the Bledisloe Cup game live preferring to have a replay of the World Series of Poker on at the time

So how does this live-streaming thing work. I've done a bit of a search and most of the links that Google comes up with look pretty shonky eg http://www.live-rugbychannel.com seems to have multiple domain names all with different pricing options that don't look very clear - sort of what I would expect if I was trying to buy Viagra online from India
