Hi Ulric,

If I have 2 hosts running pen, is there anyway to make the active pen to
constantly output it's state to a file which can be copied to the other
host periodically, so that when the active pen is down, i can start the
backup pen by importing the last state data of the master pen. The
objective is not the new pen session will at least has some "memory"
from the last one that died.
