I'd already thought a bit about this part, and wondered, isn't it more secure
to only transmit the password once you have confirmation that the encrypted
discs have arrived? The reasoning being that unless and until you send the
password out, they are no better that toasters (or /dev/urandom), so if they
get lost and no confirmation is ever given, there is no* risk of the data
Secondly, I was assuming that a phone call (providing each party recognises
the other's voice) is more secure than a fax, if you care about other
individuals inside the receiving building (possibly unauthorised)
intercepting and copying the password, as typical fax machines aren't
securely located. Although "secure password" probably contains things that
are hard to spell out, which might make that a bad plan.

lot of very fast computers. All this assumes that no-one on your side leaks
