Is this what coyotos does? I have not had time to play around with it 
but its definitely on the list of things i'd like to learn how to break 
: ) Its supposed to bring you right back to where you were in the event 
of a power failure or crash among other things, IIRC , I have a some 
hard copies of the stuff I read but hell if I know where I put them. 
Anyone have any first hand experience with it?
