Likewise. I'm another network operator and data centre user.

Defining an additional 40G MAC data-rate is just a distraction. I don't
think it's sufficiently distinctive to stand on it's own.

This sort of requirement is adequately served by 10G LAG.

If it's for attaching servers, it's going to be in the data centre, so
fibre runs are relatively short and cheap. Multiple parallel interfaces
won't be a problem, trust me.

It's sweating the existing technology, so the 4x10G server cards would be
cheaper, right? It's increasing 10G component run-rate, which should
ultimately make the silicon/optics manufacturers happy, right?
