Using a decoy operating system, with another OS hidden by TrueCrypt?

TrueCrypt provides an option to use a hidden operating system. This works by having a decoy operating system residing on partition 1, and using partition 2 as (encrypted) data storage for the decoy OS. The catch is, TrueCrypt makes it possible for the partition 2, the "outer" partition, also contain a hidden partition lurking within the outer partition's free space - which then contains the hidden operating system.
