Saving Another Ender Chest Like Inventory

[TLHPoE]

Is there any way to save an inventory to the player? Even through death?

 

I know of one way, but it wouldn't work if the player died and then the server restarted.

First, I wrote my slot contents to the player if they opened the inventory. Then, if they died, their data would be stored in a HashMap with their name. Finally, when they respawn, it gets rewritten to them.

It doesn't persist through death. :I

 

I've looked at coolAlias's tutorial on IExtendedEntityProperties but it does something similar to what I'm doing.
