> To think about what a really huge transaction load would look like, I look at the existing credit card network. I found some more estimates about how many transactions are online purchases. It's about 15 million tx per day for the entire e-commerce load of the Internet worldwide. At 1KB per transaction, that would be 15GB of bandwidth for each block generating node per day, or about two DVD movies worth. Seems do-able even with today's technology.

So Satoshi would have increased the block size by now.
