Tom, I'd turned off the "cron" equivalent on unicorn (or so I hope, Windows is... odd) the morning you sent this to reduce noise.  Apologies for that.  As soon as Nathan commits that patch I'll re-start it.  I'm also still committed to finishing up the other pieces and docs so that it's not half-done.

Nathan, thanks!  Let's coordinate when you're back online. :)
