Overall vey good suggestions ;)

Dropbox essentially creates a directory inside your “My Documents” that automatically gets synchronized over the internet. Just install Dropbox on the computers you want to sync the files to and log in to your Dropbox account, and it automatically does the rest of it.

The only painful part is setting it up so that WoW looks in your dropbox for your AddOns and WTF folders. For that I use Microsoft’s “Junction” tool that is part of sysinternals (http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx). I created a “WoW” directory in “My Dropbox”, moved my AddOns and WTF folders into that, then run the following commands from inside that WoW directory:
junction.exe “C:\Program Files\World of Warcraft\Interface\AddOns” AddOns
junction.exe “C:\Program Files\World of Warcraft\WTF” WTF

That creates links to the AddOns and WTF directories that point WoW to the directories in “My Dropbox”. Now, any time I update my AddOns or play the game and in some way change some of the saved variables in my WTF directory it is automatically saved up to Dropbox’s servers and synchronized to my other computer without me having to think about it. Even if you’re not at a computer that has Dropbox installed, you can log in to your account on their website and download an entire directory from your dropbox as a .zip file from there.

One caveat – when you install a WoW patch it seems to always destroy the symbolic links to the Dropbox directories. After installing a patch, I always have to go to my World of Warcraft directory, delete the “WTF” directory, create a new “Interface” directory, then run the junction commands again (I keep them in a .bat file in “My Dropbox\WoW” to make it easy).
