Agree, but even before that, we will meet problems of the current =
1MB/10min limit.

The calculations from the scalability link surely indicates that there =
are 2 options for scalability either go for trusted supernodes backed by =
huge hardware resources or something else would be needed. The supernode =
approach is simple and easy to implement, but it also breaks a lot of =
the nice features about bitcoin. So if we want bitcoin to stay p2p we =
need to deploy other strategies. The hash space partitioning is one of =
them. And the nice thing is that it can be made to scale even for a =
javascript based validating and fully connected client running on a =
smartphone in a bitcoin future with billions of clients and =
transactions, and still it does not exclude you from running a trusted =
supernode either.=20

Cheers,
