There always is the possibility of a worst case scenario, for what ever
domain and to my knowledge there's no strategy to cover everything. I
guess Xen's chain of thought is an attempt to work around a disaster.
IMO a keylogger in theory is indeed a good approach, but in practise
recovering something based on a keylogger could be much more time
intensive, than accepting a disaster, even for character history based
disasters, let alone from data that isn't just based on characters,
e.g. audio editing.
