One point.... If I am in a quick game with you, lets say a 1 or 2 day game, and You tell me you are on a vacation for 5 days, and the rest of my games have a longer limit, I may choose to not be on site for a couple of days myself, thinking I am safe. But then you come on anyway and make a move I don't know about, and I get timed out thinking you were not around... Just an example, and may not be all that relevant to most situations....

Maybe, If you are on vacation, and therefore cannot be timed out of any games, then neither should your opponents be timed out in your games while you are on vacation either? Just a thought.
