Has anyone worked toward compiling truecrypt for the iphone?

Almost all the data is in simple, easy to find files on the phone. How about a script that replaces all the files with links to a directory that lies within a truecrypt volume. Pull the key and your personal information is locked up. The key could be a keycode entered, a bluetooth dongle (your specific headset, perhaps), a tapped morse-code pattern on the headset button... all sorts of ideas.
