If this is what I think it is, it is good news indeed. To put it in viral terms..... : -) ..... a viral infection makes its greatest leaps when it manages to escape a current, closed ecosystem - like crossing an ocean for example. If what this 'satellite node' announcement means is that you do not have to actually have the viral wallet to act as a viral node - then they have figured out a way to escape the crypto-ecosystem, as it were. It means the network can get much larger, much faster.
