Rather than Dropbox, you could use a version control system. My entire 
.emacs.d is under git control, I can try out a library, and if I like 
it, check it in. That way, I don't really care if my elisp directory is 
dirty, I only take home what I like.

Now, that works well for lonely .el files. Two problems arise if :

1. The library is a clone of another git repository (like org)

2. The library comes from melpa (also like org)

For the first one, technically, you could checkout org git repository 
inside your .emacs, and manage it as a submodule, but they are a huge 
pain. If you pull it out you can keep everything in sync though, and 
still be able to play around with org branches.

For the second one, melpa packages change too often to make it practical 
to check them in. One solution is use cask, as recommended by Grant, the 
other one (a bit more simplistic), is to make sure that the library is 
installed on every box you use, so the sync happens at the (m)elpa 
level. I have the following code in my init.el (it comes from emacs 
prelude I think) :

  (require 'cl)

  (package-initialize)
  (add-to-list 'package-archives
               '("melpa" . "http://melpa.milkbox.net/packages/";))
  (unless package-archive-contents
    (package-refresh-contents)

  (defvar my-packages
      '(org auctex ess)
      "A list of packages to ensure are installed at launch.")

    (dolist (pack my-packages)
      (when (not (package-installed-p pack))
        (package-install pack)))))


This makes sure org from melpa is installed when emacs starts. It 
doesn't check whether it's the last version though.
