Write player status to file?

Hello folks,
This is just a shot in the dark. I have been working on a mod to create a crafting system of sorts in game. Of course, it has it’s limitations mostly imposed by the engine. To create a true RPG style crafting system I would need to be able to save the players current crafting levels to a file to later load. I do not think this is possible correct? I know you can load from .ini but that does me little good for an on going system with crafting levels and such.

Edit - Ouch just though of another snag probably making this impossible…what if they change servers without my mod?? Humm??
