We are on the same page here. One feature that we implement is the "non-sticky DOING state". Sorry for the name, we can't come up with anything for that one.
The feature works like this. When you mark a tasks as DOING that state will only last for 24hrs. After that the "worker" will be notified that the "Blimp robot" removed the DOING state. The idea is to approach the problem you are talking about. Many times projects become filled with stuff that nobody works on. I know this is a very simplistic approach but it's a start. We have a few cards up our sleeves.
