I'm sorry I'm not able to tell you precisely how I arrived in my current state of password-free, screen-sharing bliss -

Again, I also don't require a password to begin Screen Sharing. If what you mean to say is that you also don't have to enter the Mini's host name after opening the Screen Sharing application and clicking "New" in the Connection menu, or that you don't have to make a couple of other clicks to enable Screen Sharing with the Mini (e.g. by opening a new window in Finder, clicking on the Mini under the "Shared" heading, and clicking on Share Screen in the upper right of the window), then I don't know how you got there, and I've studied the Networking and Screen Sharing Preferences very carefully.
I have no interest in spending time on the phone with Apple tech support.

My plug and play comment was more in reference to the experience of using the setup once the kinks are all worked out...I think the experience is a lot easier than using a CD player in many key respects.
Here, I think we'll have to agree to disagree.
