Well... that's referred to as "Image based persistence" :-). And yes, it is one way of persisting user's data. Some people here store lots of information in their images - presentations, stuff they type up, small prototype apps, etc. It's certainly not just for developers.

If you want to get serious, there are other options for persisting image data. Google for Magma and GOODS.

Er... that's a hard one. I actually don't know. I'd probably start by installing the OSProcess package which might have something like that. I've had a quick look in my image and can't find anything.

Anybody else know?
