Sounds to me like you aren't familiar with Vim and the ecosystem. Plug-ins are your friends. Use a package manager like Vundle to easily install plug-ins. Not sure why you say vim isn't portable. I have my vimrc file on my github. Not only is vim available on all major platforms, it comes pre-installed on a bunch of systems. All I need is my vimrc file, Vundle and an Internet connection to customize any vim install to exactly how I want it.
