Regarding the first URL, I am curious how many networks will be interested 
in using a 15 metre 10GbE solution.  Even for intra-MMR xconns, it seems 
like the cable length limit will very quickly become an obstacle.  I guess 
it depends what price point copper 10Gb solutions enter the market at, 
compared to their optical counterparts.
