I definitely take advantage of the Emacs daemon, and use emacsclient extensively. However Viper just doesn't cut it for me, since I rely on a lot of vim plugins (as Locke1689 pointed out) for extra functionality. It's not just the keybindings or the modal interface. But hey, these two programs are great. I've tried other IDEs, but always end up coming back to one of those two for real work. Some things are easy in one and annoying in the other so they complement well.
