I tried googling to come up with some numbers to see how much of a worrie this should be.

Civic battery is a 51R ranging in capacity from 41 down to 28 depending on quality.
We wouldn't want to drain more then 10% in Three Days.

which means
28AH*10% = 2.8 AH's.
2.8 / 72Hrs = 39mA
39mA / 2 ~= 20ma Safty factor.

So with the backlight off.. it looks like there wouldn't be much to worry about if you use your car every other day, and a switch to shut it off if you know you will be away (or just unplug it) for an extended period of time.

Any comments on the math? That was just a quick guess..
