You are pressuring the beer out of the keg with CO2, so you don't get oxygen on the beer. Because of that it will last quite a while. It's not like the pony pump system you get when you get a Sanke keg at the store and have to keep pumping it up with air. It's just like at the local establishment where you keep pouring brew after brew, with no work besides having to drink it.
I think the longest I've gone is a couple months on one keg with no ill effects in the beer, but I had 4 kegs on the go at the time, so I don't usually have it last like that when I run 1 or 2 kegs in rotation.
