No it cannot handle a bunch of a hundred targets at only ten times the
cost. It is already parallelized. A hundred targets is a hundred times
the cost.
But let us not think small. Suppose the president says "Break James
Donald's key. I don't care how much it costs. The sky is the limit"
and they devote the entire US gross national product for a year to
breaking James Donald's key in a year.
Then they can break a 170 bit key.
But I rather doubt that they will.
