But, I was thinking about this as an encryption option -- where one could encrypt files in a way that automatically incorporates hardware information with the passphrase.  That way, if someone were to intercept a file and knew your passphrase, they would still not be able to decrypt the file unless they did it on one specific machine.

What threats are you trying to counter? The normal putting file systems on 
top of a luks container should be good enough for a lot of threats.
