saying that the port range is exponential doesn't pin it down very much.
it still requires the host to make decisions about precisely what kind
of exponential curve to use for the range, and it may get it wrong.

i suggested dropping it because it doesn't appear to me to provide
adequate information to use it correctly. i fully support having a way
to indicate that a port range is exponential if it includes *all* the
required information.

care to suggest a simpler approach?
