That's a good question, Bryan, and one I'm sure we'd all like
to explore further. Can one be legally compelled to divulge the
secret key(s) to encrypted data? Or does it fly in the face of
self-incrimination?

I CC:'d Mike Godwin on this because I'd value his views on this
topic, if he'd care to express them. Being an attorney with
considerable experience in digital matters, he may have an insight
into this that we may be overlooking.

Cheers,
