We use the Prodigy Ipod dock and use it exactly like an iServer. I put an iTouch on it and hide it away. install the Crestron Sync software on your computer and you can keep it in sync with your iTunes all the time.

Programming for the iDoc is much easier and quicker since it is a Crestron device and basically already done.

The autonomic option is great, but will be much more expensive and unless you have the stand alone server, will require a computer running their software Media Center and your itunes to keep it all working. Plus it will take more time to program.
