While nice in theory, and certainly well implemented in
TrueCrypt, the problem is that the TrueCrypt documentation
mentions the possibility. So what they will do is to
just sent you for a few years to Gitmo and if you have
not revealed the second passphrase by then (either because
you are sutubborn or becasue there is none), it will not
really matter.
In fact, when crossing the US border with TrueCrypt as
protection, I strongly advise to have the hidden container
configured and the second passphrase ready to hand over...
The problem is that nothing bad happens to them when they
torture you to hand over something you do not actually have,
as long as they have a reasonable suspicion. The TrueCrypt
handbook gives them that. Also see
http://xkcd.com/538/
So what to do? I think the only thing reasonable is to
not have encrypted data on your person in an US border
cross. This also means wiping free space with zeros,
(not random data) just to be sure. Then store the data
in encrypted form on the net somewhere safe, download
and decrypt after the border cross. Before crossing the
border again, wipe all data by overwriting with zeros.
Side note: Incredible. I would have expected these
measures to be necessary when going into the USSR of
old, but not ever for the US. How times can change...

It is a good product. Cross-platform support is limited to
normal containers, OS encryption is only available on Windows.
However there it is really done right: You can transparently
encrypt (and permenanetly decrypt if needed) an exisitng
OS installation. Did that recently for the Win7 partition
of my work Laptop. For Linux I use dm-crypt or LUKS.
