It wouldn't restrict a file to 1 device. But it would restrict the file to 1 user. This might satisfy publishers looking for a rampant sharing solution.

Still there are a few flaws here.
1. It would require allowing a "user defined" encryption key to be used in the device. So, I could change the key in my device to match the files I need to read.
2. It would well define the range of keys to perform a brute force attack.
3. People could share there SSN with other people to share books. It is basically like giving someone the "password" to a file.
4. There is no way for a store to verify the SSN that you give them. So, you could give them a bogus one, then just share it with the files on the bit torent site.
I hate to say this for the 10th time...
DRM does NOT work to protect digital assets. There is ALWAYS a way around it by someone clever enough (see Blu-Ray has been cracked). So, the only thing DRM does is inconvenience legitamate customers.
