Has anyone with 10GbE <-> 10GbE been able to transfer at or near line rate
with a single connection, or > 700MiB/s with multiple connections?  Problem
I worry about with creating multiple connections between two machines it will
create contention within the RAID that is being read from..

Are you trying to maximize this for the sake of maximizing it, or do you have an
actual application or work flow process that needs to be able to transfer a
single large file via NFS at >1 GB/s throughput?

Workflow process-

Migrate data from old/legacy RAID sets to new ones, possibly also 2TB->3TB, so the faster the transfer speed, the better.
