Secure RSS feeds
I won't even pretend that I understand all the technical details of this, but a company has obviously modified the RSS/XML concept to make it a more secure form of content delivery. So what, you might think, but this example gives an idea of the possibilities that open up: "...customers might like to get notification from his credit card company when a transaction has cleared."
I work with a lot of large organizations and there's been a major shift the last two or three years. Security never used to be a discussion that interested Communication Directors or Web Editors (the people I talk to). Now, security is one of the basic questions. And that's why secure RSS use is a major step for RSS adaptation. If it's the solution above or another one, I don't know.
