Simple. I would like to see a plugin which adds a world guard flag that forces player to have keep inventory rule on. However as soon as he leaves in an event of death, teleportation ect he should no longer have this power. This is particularly useful in making dungeons and safe pvp areas. Anymore questions or suggestions maybe a plugin that does this post them below!
Google "worldguard keep inventory flag" and first link http://dev.bukkit.org/bukkit-plugins/worldguard-keep-inventory-flags/
Never mind found this plugin: http://dev.bukkit.org/bukkit-plugins/worldguard-keep-inventory-flags/ Testing if it works now!
