Re: IEEE 40GE & 100GE

Chris,

Those were straw-man numbers.  The point is that eventually it all
becomes a commodity and mass-produced, and I'd like to see the stuff
that would be maximally useful to us be the commodity that benefits
most from the mass production.  Hence my preference for the 10km optics.
