Tim, I actually use TruCrypt now to do exactly what you speak of.   I pre-allocate a fixed virtual disk, and use one 
passcode for one section of data and a different passcode for a different section of data.   It is impossible to 
determine if the disk is set up in this manner, and impossible to tell which section of data is being used.   It is 
actually quite easy to do.

What really concerns me is how ignorant our government is to issues of encryption and technology.  If I am arrested and 
my laptop seized, and am compelled to give up my "encrypted files," then those factors, as well as the data, become 
evidence.  When I give up one passphrase that decrypts a collection of my own artwork of nuns riding My Little Ponies 
leading a cart of newly adopted Cabbage Patch Kids, it will be disclosed as evidence in trial that I not only 
cooperated 100% with authorities, but that no incriminating evidence whatsoever was found in my files.  This would work 
in my favor, obviously.

Considering encryption keys to be analogous to keys to a safe containing documents for evidentiary purposes is, quite 
frankly, stupid.  Prosecutors who think they are doing the world a favor by establishing precedence that actually can 
be used to a criminal's advantage while reducing our constitutional rights should be forced to work in other 
industries.  Douche bags.

Supposing that the US courts decide that people aren't protected by the 5th
ammendment, one solution for protecting your files might be:

Encrypt everything using a one-time pad.  When compelled to provide the
one-time pad, provide a pad that decrypts the data to something else.  Any
resulting plaintext can be crafted.

Ok, sure, that seems pretty painful (storage/protection of pad, etc).
I guess the only other technical solution would be steganography.
