No. I think the reason goes as follows: for the intended purpose of `emacsclient`, the time needed to start Emacs itself makes an ELisp implementation useless, and for other purposes you can generally have a separate server process per client process and it's just as easy if not easier to then use `start-process` and a ad-hoc communication protocol rather than having to reuse the protocol used for `emacsclient` (which is neither very convenient nor very extensible). That also saves you from the problem of choosing a socket name/number for the communication between the two processes and dealing with the associated problems of security. Stefan
