For the purposes of this issue, I think either solution would probably 
work. It probably depends on what people think on emacs-devel.

Right, invoking the main Emacs instance as a daemon (i.e. when 
--alternate-editor is the empty string) works pretty differently from 
invoking the main Emacs instance directly (i.e. when --alternate-editor 
is "emacs" or somesuch). In the former case, emacsclient starts "emacs 
--daemon" and then tries to reconnect to the daemon; in the latter, it 
just takes the arguments passed to emacsclient and forwards them (well, 
some of them) to emacs. The end result is that it runs "emacs '(message 
"hi")'", which isn't correct.

It'd be nice to fix the behavior of "--alternate-editor emacs" so it 
passes the --eval flag along too. This might be tricky though, since the 
semantics of --eval aren't quite the same for emacs and emacsclient. For 
emacs, --eval means that just the next argument is Lisp code; for 
emacsclient, --eval means that *all* subsequent (positional) arguments 
are Lisp code.

In practice though, I don't think fixing this is actually *required* to 
fix the issue of how org-protocol is handled. It only causes issues for 
the subset of people who use "--alternate-editor emacs" or something 
similar.
