OK. You can see why I'm wondering. If the new crop of wonder
algorithms are biased toward small packets (because in the regular old
Internet large packets generally means "bulk" i.e. "it's okay to take a
while"), then they aren't much help to us and in fact we'll have to
actively campaign to keep the option of turning them OFF. Any ideas
what to do about this?
