Bill Sanders has done it again - and yes I know I am slow to blog it. Nevertheless his new book in PDF format, published by O'Reilly and titled Learning Flash Media Server 3, comes highly recommended. On over 250 pages it covers a lot of ground to get you started with FMS3 and also quite deeply into more advanced topics. From installation to setup over SharedObject and streaming video and audio to server side programming, every reader will get something out of this book.
You can get more info on it at O'Reilly and also order it there for a mere USD $19.99.

There is a Windows and Linux (RHEL) edition. You can get it to run on other flavors of linux, but it may require tweaks which Adobe doesn't offer support for. Unfortunately there is no Mac version, so you would have to run it in Parallels or VMWare if you wanted to develop locally on a Mac.
2-Way Audio-Video, I did the Easy1.as module, but when I test it, I get "Cannot
find the file://C:\Program Files\Adobe\
Flash Media Server3\applications\easy\Easy1
even though the files are located there.
I test the Easy1.as file for script errors and find none. But when I publish the fla file, I get error 1046: Type was not found or was not a compile-time constant:
NetStatusEvent. (line 34).
