I thought so too. :-)

At the moment, no I can't tell you much, but it wouldn't help you all that
much, as far as I can tell. CGD does not support booting at startup (as
GELI does), so encypting / isn't an option for you. Making you
installation "invisible" would boil down to having / on an external device
and "only" encrypting /usr and /var. Most of the data on a drive will
actually be in those two directories, but having / on a CD can be a pain
if you want to change any of the settings and if you have / on some other
device (some type of flash module for example), you won't be able to
remove that after booting.
