Do you think it will make a bit of a difference at the MPI level ?

There are some characteristics of long distance networking that you will
never change, like the speed of light. IPv4 or IPv6, don't expect good
performance running MPI codes across the Internet, unless there is no
communication. 
When the Grid Computing community will finally realize that... :-)
