I have two macs that both run emacs. I have a private git repository for my .emacs.d folder (an old mirror can be found here: https://github.com/elarkin/.emacs.d ). I have taken special care to make sure that the init.el file is readable, and can be used with a fresh copy of emacs (without any packages installed) and everything works just fine.
If you want to try it, just brew install emacs --cocoa and clone the repo to ~/.emacs.d
A coworker and I trade snippets of elisp for our configurations over email, and whenever I update the repo on one machine, the other needs to pull it down and evaluate the file (eval-buffer)
I have not found sharing customizations of emacs to be very difficult, but I also don't use any god packages like emacs starter-kit, or prelude (which I haven't heard of). I have let my configuration grow organically.
My emacs automatically downloads and installs all my used packages on first startup on a fresh install. Literally all I have to do on a new box is clone my dotfiles and start emacs.
