encryption

I would like to have a disk that:

has Ubuntu installed
is fully encrypted
is setup in such a way as to make denial of the existence of the Ubuntu install plausible

Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os

The alternate installer for Ubuntu provides the first two features but not the last.

I imagine that plausible deniability would be achieved by, at least:

Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one.
Moving any unencrypted data (such as /boot) onto a USB stick

Are there any programs out there which support this feature set for Ubuntu?

I have an idea for encryption that I could program fairly easily to encrypt some local text file. Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike?
