I think it's a good idea, thought about it before and came to the conclusion that it sadly won't work if the pod is worth $. As Jammi said, people will farm each other and themselves, and it would lead to a dramatic increase in random PVP for the sake of collecting people's pods and selling them off for profits.
Worthless pod dropping on death would be cool though.
Off-topic: I'd really like a killboard with detailed statistics.
