    and how is it infeasible now?  you may want to look at the address space
    the roots and gtlds are in now before answering.

**  and do note that the long timeout is not relevant if the box is not

    the golden space snake oil has been available to roots for some years.
    how many use it?  perhaps root operators have actually studied the
    issues and voted with their feet?
