Presentation on Perian

Last night I gave a presentation to CAWUG about Perian. It's intended for developers, and it was received fairly well. I've posted the contents of the presentation so other people can take a look at it.

The other presentation was Rentzsch on NSXReturnThrowError (to be renamed soon), which is a horrifying set of macros that make error handling in mixed Cocoa/Carbon/C++/posix code easier.
