Sounds like a good idea.
Guessing I'd need a variable option to turn this on, and another to indicate the room number of the locker to deposit in. The feature wouldn't be that hard to write, but handling all the possible error scenarios would be more difficult. i.e. locker room is occupied, locker is full, locker is blocked by debt. I'll have to look and see if there is a script already written to automate using lockers and if so it would make the whole thing easier. If there isn't I might write a locker manager script to encapsulate those functionalities and then just use it with sloot4.
