How is IPv6 "so different" than IPv4 when looking at Layer 3 and above?

(Certainly ARP vs ND is different.)

I didn't say it was different 'when looking at layer 3 and above". I said it's different from IPv4. At the IP layer.

		At the IP layer just being different is 90% of the trouble. Being less ambitious would have some upsides and downsides but not seriously change that.
