I am wondering if any other institutions are using the self-serving safe deposit box method, referred to as the "bus locker" concept?

I have read the related articles on BOL titled "Self Service Safe Deposit Boxes Part I and II", and "Who took the SAFE out of Safe Deposit?" Both articles are basically saying that this is a liability waiting to happen.

Are there any institutions that found this to be sucessful? If so, would someone be willing to discuss procedures or how their process was set up?

We are in the beginning stages of contemplating this new system, therefore any feedback is beneficial.
