This book will help you master Back to My Mac, a feature introduced in Mac OS X 10.5 Leopard that lets you remotely access files and remotely control the screens of multiple Macs that you manage or own.

Introduction
If you thought this book title was interesting, then you probably own more than one computer, and your computers are likely located in different places—whether just down the hall or halfway around the world from each other.
I'm no mind reader, and you can easily determine how I predicted your computer ownership. It's increasingly the case that when we're on one computer, we find that we need files from or need control of another computer. Fortunately, Mac OS X 10.5 Leopard has added a significant tool to our arsenal that can reach out over a local network or the Internet: Back to My Mac.
Back to My Mac uses a host of industry standards and Apple-developed protocols to create an intertwined web (as in a woven web, not the World Wide Web) of services. It uses these services to create a connection between Macs for the purposes of remote file sharing and remote screen control. The "key" to this connection, so to speak, is a shared .Mac account.
Leopard's somewhat unique twist on existing third-party and Apple technologies is in allowing file sharing and remote screen control via "tunnels" that can reach through home and office wireless and broadband gateways and past network obstructions.
Apple would like to say that one or two clicks turns on these services. However, as with any set of tools that relies on the Internet, there's more beneath the surface.
In this book, I show you not only how to set up your network and your connected Macintoshes for the best results with Back to My Mac, but also how to troubleshoot problems, determine whether Back to My Mac can even work for you, and overcome stumbling blocks.

Do I need a .Mac account to set up Back to My Mac?
Yes. A MobileMe account will work too, once MobileMe is working in July.
What about MobileMe?
In early June, Apple announced that .Mac will be transitioning to a new online service, with enhanced features, called MobileMe, in July. We have confirmed with Apple that the functionality of Back to My Mac will not be changing right away in MobileMe. It is likely, however, that the text labels in the interface for configuring Back to My Mac will change, so, for instance, in System Preferences, you'll probably be working with a MobileMe pane, not a .Mac pane. Obviously, we plan to update the ebook to include those changes (but not before our summer vacation!). Meanwhile, we know there are folks who want help with Back to My Mac right now, so we decided to go ahead and release this ebook.
Can I make an AirPort base station from before 2003 work with Back to My Mac?
Glenn suggests that you not try. Specifically, he wrote in the ebook, "If you have a pre-2003 AirPort Base Station, any of the two 802.11b gateways (with the alien ship design) that Apple produced from 1999 to 2002, your best bet is to upgrade. You won't get the performance or features you need from it, and you're using outdated security, to boot. A used 2003 AirPort Extreme Base Station with the latest firmware—always a free update from Apple—is better than any of the pre-2003 models."
What if I want to know about screen sharing through other methods, like iChat?
