So Bitcoin's scalability relies on a mixture of writing new software when it's needed ("The core BitCoin network can scale to very high transaction rates assuming a distributed version of the node software is built. This would not be very complicated.") and in future switching to a two-tiered structure with "supernodes" transmitting data between themselves at a rate of >1GB/s. While I suppose that it's good that someone is thinking about this, it does not inspire confidence in bitcoin's ability to scale - the fact that it's theoretically possibly to write software allowing it to scale is very different from someone going off, writing this software, and demonstrating that it does scale.
