It's always a surprise when the CO2 tank goes dead. It really shouldn't be - we know that a 5lb CO2 tank serves 5-7 half-barrel kegs. The problem is that we don't know when a new CO2 tank was hooked up, nor how many kegs have been served since then. After the keg history is implemented (issue #2), we can do this. Let's do it so that we can anticipate when we'll need to swap the CO2 tank.
