• I just set up a good solution for this, it requires dropbox. I am currently using this to sync plugins and settings across ~5 different sublime installs on windows, linux, osx, and a few vm's.
• Step 1: use PackageControl to manage all your plugins, its awesome.
• Step 2: Add a "Sublime" directory to your root drop-box directory (I replicated the full directory structure for the hell of it, {DropBox}/Sublime/Packages/User). Make sure sublime is closed, and move the contents of {SublimeRoot}/Packages/User in to the dropbox directory you just made. Delete {SublimeRoot}/Packages/User, and replace it with a symlink that points to {DropBox}/Sublime/Packages/User.
• Use this same process on every computer where you use sublime, it accomplishes 2 things.

1) The contents of your User/ directory are synced, so all your custom settings are the same across machines.

• 2) Every time PackageControl starts up, it checks the Package Control.sublime-settings in your User/ directory. If if finds a plugin that should be installed according to the settings, but isn't actually installed, it automatically installs it, no questions asked.
• Setting up another computer with this solution simply requires sublime and package control to be installed, then just delete the {SublimeRoot}/Packages/User/ directory and point it to the copy in dropbox with a symbolic link. Next time you fire up sublime, package control will automatically install all your plugins.
• Creating the symbolic links: execute from the {Sublime}/Packages directory
• Windows: mklink /D .\User C:\Users\
  
  \Dropbox\Sublime\Packages\User
• Linux/OSX: ln -s {DropboxRoot}/Sublime/Packages/User ./User
