Actually what I meant about the speed was that if it's real and sustainable that's a damn good transfer rate for USB, even USB 2 isn't usually that fast on average. I have cable internet myself, so the internet side of that isn't a big deal to me.
I'd like to see something like this used for networking in an environment where ethernet is not available, or as a secure and isolated networking path in an environment that already has broadband running via ethernet (in other words a file transfer path that is isolated from the household LAN by virtue of not sharing that hardware pathway) - i know this can be done with multiple ethernet cards, but still... could be cool.
