Thanks!  DDB capture output, scripting, and textdumps were pretty much what I 
had in the queue for DDB at this point.  I'll see if I can't come up with some 
stuff, and look forward to hearing about how people use these ones.  I'll also 
happily accept bug reports...

Textdumps should open up the door for some interesting things in terms of bug 
management--I'd love to see someone put together some rc.d/rc.conf parts to do 
automated crash report submission (disabled by default, of course) and a 
database to hold the results.  I suspect a moderate number of panic reports 
are lost on the basis that filing a proper bug report is fairly difficult (get 
out kgdb, etc), or that the boxes quietly reboot and the core dumps rot on 
disk (to be deleted when space runs out).  Perhaps hoovering up those 
textdumps, especially if we can correlate them with one another using some 
automated processing, might be quite informative.  Or just a good time sink 
:-).
