I'm a bit skeptical. You're talking about 1.7M per second that needs to be sent to every client on the network, right? Since as I understand, each client needs to examine all the blocks to verify the integrity of the chain. And can clients really afford to compute the hash of a couple of megabytes per second? Or would most clients just trust someone else to verify the integrity of the bitcoin system?

Drawing an analogy to the Gnutella network...
At Visa/Paypal transaction rates, most bitcoin clients will be leaf nodes, that send and receive transactions, but don't bother with the block chain.
Beefy ultrapeer nodes would be the ones storing transactions, building blocks, monitoring and verifying the block chain, etc. They are incentivized to do this with transaction fees, which non-generating leaf nodes would not receive.
