	 I'm not sure this is how it happened, but the person (maybe there's
	 more than one?) who did this is a cypherpunk, who will identify
	 himself if he wants.  He also wrote a paper on this.  The first
	 version of the paper had the private key at the top of the first page,

??  As far as I know, Sun's secure RPC uses Diffie-Hellman with a
192-bit modulus.  LaMacchia and Odlyzko solved the discrete log problem
for that size, but there's no single private key to disclose.
