Yeah, but remember, in the world we're heading to, presumption
of innocence is worth even less, than President's word!
Then it will be *your* responsibility to satisfy the
Inquisitor, or he might not let you out from his
building, where you were invited to explain
yourself and your messages. (:-) (:-(

And the response to this will be: "Sure, here it is, this
nice hardware implementation. You may have it, if you
wish!" (:-) It's fool-proof, but still the Big
Brother might dislike your desire to play with
those bad random generators, and decide,
that you better be kept in KZ-camp...
Probably creating a GIF/TIFF/whatever file yourself,
with normal consumer-grade equipment (noise-prone :-)
and substituting it's LSB (or whatever certainly lies
BELOW the noise floor) with bits of the message, does
sound like the best choice today.
1) Doesn't look suspicious, no more, than
"traditional" sending photos of your
house, family, yourself...
2) Has enough of bandwidth to communicate
reasonably large personal messages
(though a binary og PGP might
not fit into a "normal"
GIF file :-).
3) Requires only widely available consumer
appliances (Camcoder, digitizer, .....).
4) The image doesn't have to be known to your
correspondent in advance (a big one!).
1) Somebody has to do it, to write code, to
buy a Camcoder (:-).
2) May lead to outlawing of ALL the image and
sound transmission via electronic media,
if Big Brother gets really annoyed (:-).
