There is no silent opening of Ender Chests. I suppose it wouldn't normally be required to open one since you should already know what's in it. But just thought I would post it.

Minecraft: 1.3.2
Craftbukkit: 1.3.1 R1.0
Plugin: 3.12

Thanks. It's on the todo list, just didn't get around to adding it here :)
