there are several paren'ed parts to the Controller: eg. @interface Controller (ChatFunctionality) @interface Controller (NSNetServiceDelegation) the details of the paren'd things wasn't stated in the article. I didn't have so many subsections and mine still worked. What are these parens, some sort of protocol thing?

  Not a protocol. It's called a Category. It's basically a way of extending classes. It's usually used with classes you don't have the source to but want to extend, but in this case it's simply a way of compartmentalizing the methods.
