A very simple backpack plugin for public or private Minecraft survival servers. When the player's ender chest is full, there's an additional backpack that works exactly like an ender chest, but with the command /bp

Commands:
/bp - Opens the backpack
/bp <player> - Opens the specified player's backpack

Permissions:
playerbackpack.backpack - Access to use the backpack
playerbackpack.admin - Access to seeing other player's backpacks
