What type of hardware and protocol changes will be required? Will it run on top of existing hardware and protocols using existing layers? Will it be like adding a new Layer 3 protocol? Will it be like IPv6 and require new hardware? IPv6 does quite a bit more than IPv4, but people still have seemed to be rather loathe in giving up on IPv4. So how it is implemented and what requirements to make it work are there will be a big part in determining its attractiveness and adoption.
