I will say that if amazon would get off the dime and support IPv6, it would make a significant difference. 

Per Microsoft public statements, they are now moving address space allocated them in Brazil to the US to fill a major 
service shortfall in Azure. They’re not the only kids on the block with that problem, but are perhaps the one most 
publicly reported. To my way of thinking, having services like that adopt IPv6 and tell their customers that they need 
to access the service using IPv6 would go a lot farther that residential service in pushing enterprise adoption.

http://tools.ietf.org/html/draft-anderson-siit-dc gives a fairly clever way to make it possible for the service itself 
to be IPv6-only and yet provide IPv4 access, and preserve IPv4 addresses in the process.
