This is the actual material being contested:
1. A method of communicating between computers, comprising the steps of:
creating a message at a first computer, said message including a reference to a predetermined location;
transmitting, by the first computer, said message to a second location; and
receiving said message by a computer at the second location;
decoding said message by the computer at the second location by retrieving data from the predetermined location, automatically by a single application, without requiring user interaction, into the computer at the second location.
So actually this looks like a dandy malware vector. Send an email with a link; the receiver then downloads the content from the link without human intervention.
I'd be upset if my email client was doing this.
