I don't think so.
FCoE is meant to run ontop of Enhanced (or Datacenter) Ethernet, not a stantard one will all know & use widely today.
Two key differences vs. bog-standard TCP/IP are it is a) loss-less, b) packets delivery order is guaranteed (as in 'traditional' FC network).
The starting point speed-wise for Enhanced Ethernet is 10Gbit & I'd guess it will only grow over time!
