You probably were thinking of the new Foundry MG8 there?

Force-10 have a crossbar switch with pretty deep packet buffers too.

Long-haul fiber is not that cheap for everybody, but I agree that adding

Why would 10GE not be WAN/core?  Link speeds are supposed to go up when
nearer to the core, aren't they?
