I read it, too. It reminded me of a novel i read online in 1994. It could have been 1993. I have the distinct memory of sitting at my indigo workstation at the lab, my back to all the electronics, reading a cyber-espionage novel. There was a good bit about the security of satellite phones, an introduction of how to use pass phrases as mnemonics for non-dictionary attack passwords... escape to a Hawaiian island....?
I asked Doctorow, who kindly replied that he didn't write it. You wouldn't have read it and remembered, would you? I have no memory of any distinct key words to track it down, and i'm not up to scanning through the "What's New" archive or googling through Usenet.
