Can't recall if I thanked Doc Sober for raising the LifeRing approach, but thank you anyway.
I imagine it's popped up occasionally on Sec Connections over a few years, but hasn't quite got the 'purchase' of the other non-AA style approaches.....a thousand possible reasons for that, but who cares what they are, as long as some people get to hear of it and investigate it for themselves. We can never have too many recovery paradigms to try out and work with, I reckon.
