Saga Idea -- Fishery

Would it be possible to create a "Fishery" that allows the player to have a chest that fills up with random objects such as

- Ender Pearls
- Wooden Planks
- Wooden sticks
- Gold Nuggets
- Fish
- Fishing poles (damaged)
- Leather
- Parts of armor [Strictly Leather]
- Buckets
- Shears

This would be a neat/usefull thing for players to create, but it would have to be near water, would this be possible?

I love it, but this seems a lot like something you can add to buildings. the command (as i recall) is /baddstorage which spawns items in a chest according to the building

I definitely can add new buildings like that.

But why fishery?

Also, since Saga is available on bukkit dev, then the buildings I add must be logical.

Why not a fishery? They were around during the early settlements :3

Pluss, I just want a lot of junk washing up in a trunk.
