Daily/weekly/monthly output aggregation

[Damian Gerow]

I've already received a handful of responses, private and public, to this
posting.  Which leads me to believe that:

    a) People reading isp at freebsd.org have nothing better to do with their
    time.

Or:

    b) This is a pretty big problem that nothing has addressed yet.

Running on the assumption that the answer is tending towards option b, I'll
poke around, and see if I can find anything that may be in use.  If not,
I'll send some notes to those who have offered help, and start working on
something relatively soon.
