Emacs 23 on OS X - use multiple instances or emacsclient?

I wonder if anyone has any recommendations on setting up emacs 23 on OS X. I have been using Linux / Windows for a while, and there, I would just open many instances of emacs and they were standalone - for example, I could have two separate files in separate frames, each with its own R, Python and / or shell. I think this is disapproving (?) - but he kept the working directory for each script file separately, which I liked.

I understand that there is some advantage in configuring (server-start) in my .emacs file, and calling emacsclient instead of emacs is now the preferred way (?). I found this thread that facilitates this through Applescript: Emacs 23, OS X, multi-tty and emacsclient

But I wonder if this is the only way around this - when I open two instances of emacs on OS X, it gives me an error:

** CFMessagePort: bootstrap_register(): failed 1100 (0x44c) 'Permission denied', port = 0x3803, name = 'org.gnu.Emacs.ServiceProvider'

but it opens a new frame that allows you to edit files. I understand that for vim on OS X there is something called "mvim" that allows you to run multiple instances of vim, but is there something similar for emacs? Sorry for the old question - in general, I think these are the questions for which I would like to request your experience:

(1) Is "emacsclient" an expert method and (2) if not necessary, is there a way to get multiple instances of emacs 23 (and not just frames) running on OS X?

Thanks! -Stephen

You can run multiple instances of Emacs with multiple files or directories:

emacs-ide ~/Projects/project-1
emacs-ide ~/Projects/project-2

The script also sets the window name according to the directory (project) or edited file.

Using

open -a -n /Applications/Emacs.app

failed for me with a pop-up window "Emacs quits unexpectedly". (OS X Yosemite 10.10.3, Emacs 24.3.1 x86_64-apple-darwin)

As a workaround, I installed Aquamacs as well as Emacs, so at least I can have two copies.
