For those thirsting on more detail and background information about Webcasting and Streaming, may I recommend the following titles:

Hands-On Guide To Webcasting, Internet Event and AV Production, Steve Mack & Dan Rayburn, Focal Press, ISBN-13: 978-0-240-80754-6, ISBN-10: 0-240-80754-5

This book is a requirement for the follow-up publication in second edition:

Hands-On Guide To Streaming Media, An Introduction to Delivering On-Demand Media, Joe Follansbee, Focal Press, ISBN-13: 978-0-240-80863-5, ISBN-10: 0-240-80863-0

Both books fit well to the curriculum offered at the Webcast Academy, and offer a few tips that Interns often ponder on.
