"Feds probe alleged hacking theft of Romney's tax returns,"
http://news.cnet.com/8301-1009_3-57506843-83/feds-probe-alleged-hacking-theft-of-romneys-tax-returns/

A follow up message posted yesterday [on PasteBin] said the files
[Romney's 1040 tax returns] were accessed from the PWC [Price
Waterhouse Cooper] network file servers and would be released in
encrypted form to major news media outlets. The encrypted key to open
the files would be released publicly unless Romney paid the hackers $1
million by transferring that amount -- in the virtual currency called
Bitcoins -- to a specific account. However, if someone else wants the
information to be released publicly sooner than that, they would need
to transfer the same amount to a different Bitcoin account, the
message said.

Re: [cryptography] Can there be a cryptographic "dead man switch"?

And make sure there are multiple internet connections to the hidden servers.

Good argument.  Thanks.  It makes Natanael's solution, or some variant
of it, all the more appealing.  Keep Natanael's servers secret, such
as on scattered Virtual Private Servers.  They read the Grantor's
signed messages from a message pool such as alt.anonymous.messages and
use that channel also to communicate among themselves, outputting via
anonymizing remailers.  The adversary wouldn't know which of the
world's internet connections to pull.  When the servers agree that the
Grantor is dead, they release the secret, encrypted all the while with
the Trustee's key.
