thanks - I've never seen one.  I know 16k units are possible,
and I don't doubt you're right about their rackiness.
but I thought the 16k unit was considered sort of non-unit/fractional - 
does it being that size mean a dimension of the interconnect mesh
is unpopulated or something?

thanks, mark hahn.
