IMHO emacsclient should be the way.
It could work like this: 
emacs --daemon
then use "emacsclient" to create window system frames, and "emacsclient -t"
to create terminal frames.
(There is a functionally equivalent workaround for the missing --daemon
functionality that people are using now: start "emacs -nw -fserver-start" 
in a "screen" session, and then suspend the "screen" session)
Maybe at some point emacsclient should be folded in emacs.

Both NS and X are not supported in one executable, never heard of anyone
planning to support that.
You can use terminal frames now when logged in remotely (via emacsclient
-t), in a 256 color terminal they work pretty well.

Unfortunately terminal frames won't work very well in this setup... 

Hope this helps.
