I was not aware of any other documentation than this, but searching google
groups turned up this link:
http://groups.google.com/group/gnu.emacs/browse_thread/thread/dcb0343a012b69dc/86931742d045b117?q=GNU_NODE#86931742d045b117
to a posting from 1989 that is, I believe, the origin of the implementation
in xemacs.
My understanding is that gnuclient uses four environment variables to
control the way that it connects to the server:
GNU_PORT and GNU_HOST to identify the location of the server
GNU_SECURE for authorization
GNU_NODE (as described in this thread).
As you probably know, emacsclient is different in that it uses a single file
in .emacs.d/server to identify the server's location, and for authorization,
I believe.
On my machine this file looks like this:
127.0.0.1:41055 15289
R`HIRQ;aQxEG.U7.u.VExqpQLga@4kL4h_xH|'n1",)SBf:1<Cu('ad1kIi1=yqZ
I considered using a more descriptive name than GNU_NODE
(EMACSCLIENT_PREFIX?) but ended up with GNU_NODE just for compatibility,
although given all the other differences the compatibility argument for
doing things this way is not very strong.
Is gnuclient the only other program using such

I think so. I'm not aware of any other program that uses GNU_NODE in this
(or any other) way. The idea and the environment variable name were
entirely inspired by gnuclient in my case. GNU_NODE_EXCLUDE is, to my
knowledge, a new extension.
