Hi Zooko,

I tried following up to cryptography at randombit.net but haven't taken the
time to figure out which hoops to jump through to make messages actually
appear there. Anyway, you have to read the "parent case" section of the

  This is a continuation of PCT/CA95/00452, filed on Jul. 31, 1995,
  which is a continuation-in-part of Ser. No. 08/282,263, filed on Jul.
  29, 1994, now abandoned.

This means that the patent can survive prior art after July 1993, but it
also means that the patent expires in 2014.
