|So it seems to me that ESDs are similar to PI addresses (i.e. GSE |doesn't eliminate the USE of PI addresses, but does get rid of them |in the transit space).
This is exactly where I have to disagree. The ESD is simply not an address. It is a wholly orthogonal namespace. While it is globally unique, it shares no other properties with a PI address that I can see. |How is GSE similar to NAT? GSE does pure translation on the routing bits. In a NAT environment, the routing goop is translated into an RFC 1918 address. In GSE, the routing goop gets zeroed out. GSE is better than NAT in that it does provide a real identifier that applications can now exchange freely, so that much of the translation ugliness within NAT (e.g., FTP port commands) can go away.
