I use ZNC to connect to IRC, and since ZNC seems to have the unfortunate characteristic of making me create a new "login" for each server I want to connect to (i.e Freenode and Quakenet), when erc starts I have a bunch of buffers all named the same thing.

My erc config looks like:

(defun djcb-erc-start-or-switch ()
  "Connect to ERC, or switch to last active buffer"
  (interactive)
  (if (get-buffer "example.com:60667") ;; ERC already active?

    (erc-track-switch-buffer 1) ;; yes: switch to last active
    (when (y-or-n-p "Start ERC? ") ;; no: maybe start ERC
      ;; I use ZNC so I need to hit my server
      (erc :server "example.com" :port 60667 :nick "nick1")
      (erc :server "example.com" :port 60667 :nick "nick2")
)))

How can I get it to start and alias the server buffer names for nick1 to Freenode and nick2 to whateverrandomserver?

This should be simple, but ERC is heavily magical around the mode line so it's not; I tried hooking erc-mode-hook and renaming the buffer, but there's an automated mode line update that instantly stepped on my change. Best advice I have is to spend some time staring at the definition of erc-update-mode-line-buffer and frowning mightily; it seems like some around-advice that plays with the values in the format spec might work well, but I ran out of time to play with it before I found something that actually does the job.
