First, my point was at least as much about "change server.el rather than
creating a new emasserver.el" than about "modify emacsclient.c instead
of creating a new emacsclient.el".
One of the reasons for emacsclient.c is that it should be faster
to execute.  Now this is not necessarily the case and for other reasons
I think it might be worthwhile to implement an elisp version of the
As far as portability is concerned, it shouldn't be that bad since it's just
some TCP socket code in emacsclient.c which AFAIK will only require some
header-inclusion-tweaking to get working: the code in itself will hopefully
work in both Unix and w32 environments without too much trouble.

Yes.  Much like Xauth (which gnuserv uses).
