Switching to tor-talk.

Is that important for Strongbox?  I don't think Strongbox's threat model
needs the document upload server to *be* anonymous.  Strongbox is run by
the New Yorker.  If you want to find their upload server, just look at all
the IP ranges the New Yorker leases.  Or subpoena them, or serve them with
a warrant.

If you were talking about Wikileaks, I might agree - it might be important
for them for their servers to be anonymous.  But then again, it apparently
*wasn't* because IIRC they never ran a document upload service soley on a
HS.  (They may have run one, but everything was also available on the
general 'net, again, IIRC).

I think for all (or most?) of the document leaking services we've seen so
far, the anonymity of the server isn't terribly important, it's the
security & anonymity of the sender that must be preserved at all costs.  In
that regard, HS are still good, because as you said "sources are forced to
use Tor, [with] end-to-end crypto without relying on CAs".
