I'll throw in an observation on arp behaviour on wifi / HomePNA: neither
protocol provides reliable delivery of broadcast traffic, while point to
point traffic is reliably delivered. If arp traffic is not sufficiently
aggressive when a connection is first used, the user can end up waiting
some time until one of the broadcast packets finally gets through. Doing
an exponential backoff will make this significantly worse, unless the
initial timeout is sufficiently small.
