Ben,

Thinking about this some more, I think I can propose a minimal edit to
the section 3.4.2:

    <t>Creating a discovery protocol that has the desired security
    properties may result in a design that is not efficient.
    To perform the necessary operations the protocol may
    need to send and receive a large number of network packets,

>>>    or require an inordinate amount of multicast transmissions. <<<

    This may consume an unreasonable amount of network capacity,
    particularly problematic when it is a shared wireless spectrum.
    Further, it may cause an unnecessary level of power consumption
    which is particularly problematic on battery devices,
    and may result in the discovery process being slow.</t>

That is, just a subtle hint, but enough to draw attention on potential
issues.

Would that work?
