Yes, that's a proper consideration, since some shells don't.

Okay, here's what I've ACTUALLY been using these past months ...

; x-clip support for emacs-nox / emacs-nw
(defun my-copy-to-xclipboard(arg)
  (interactive "P")
    ((not (use-region-p))
      (message "Nothing to yank to X-clipboard"))
    ((and (not (display-graphic-p))
         (/= 0 (shell-command-on-region
                 (region-beginning) (region-end) "xsel -i -b")))
      (error "Is program `xsel' installed?"))
      (when (display-graphic-p)
        (call-interactively 'clipboard-kill-ring-save))
      (message "Yanked region to X-clipboard")
      (when arg
        (kill-region  (region-beginning) (region-end)))

(defun my-cut-to-xclipboard()
  (my-copy-to-xclipboard t))

(defun my-paste-from-xclipboard()
  "Uses shell command `xsel -o' to paste from x-clipboard. With
one prefix arg, pastes from X-PRIMARY, and with two prefix args,
pastes from X-SECONDARY."
  (if (display-graphic-p)
     ((opt (prefix-numeric-value current-prefix-arg))
      (opt (cond
       ((=  1 opt) "b")
       ((=  4 opt) "p")
       ((= 16 opt) "s"))))
    (insert (shell-command-to-string (concat "xsel -o -" opt))))))

(global-set-key (kbd "C-c C-w") 'my-cut-to-xclipboard)
(global-set-key (kbd "C-c M-w") 'my-copy-to-xclipboard)
(global-set-key (kbd "C-c C-y") 'my-paste-from-xclipboard)
