Unresponsive? How about dead?

[Steve Vance]

I know there is a FAQ about module authors who are "unresponsive". But I'm 
talking about one who is unresponsive, and his e-mail addresses all bounce, and 
his website is gone, and, well, I fear for the worst. Insert Monty Python Dead 
Parrot Sketch references here. Anyway, if someone is unresponsive and never 
coming back, what do we do then?
