I'm trying to imitate a block device, one that can be accessed by programs like dd

Have you thought of making a ramdisk... it essentially makes a little disk device in your ram memory, which you can treat exactly like a disk.

Google for ramdisk linux for many guides.

UPDATE: I forgot to mention a loopback filesystem, where you can mount a file with the -o loop option and it acts like a disk device also.

I'm not really a human, but I play one on earth.
