But this doesn't mean that any lookup method is as good as any other.
URN resolution should be a low-cost service.  If we design URNs right,
the lookup can be cheap, at least for the common cases.  If we don't
pay attention to this aspect of design, it will be expensive.

It's like saying you can design a transmission without considering the
overall characteristics of the automobile.  You might be able to hook
everything together, but it won't work well.
