Hello everybody,

I am aware that it is possible for two people to work on one
document using the "File/Frame on other display" if the
other person accepts X connections to his/her display. But
the session has always to be started by let's say person A
offering a window to person B. Is it possible that person B
starts up his own emacs session and somehow connects to A's
session sharing buffers with him?

Thanks a lot for your help,

Tobias

Funny you should mention that. I've got a couple of students doing
exactly that for a class project this semester. I'll let you know
when/if they produce something usable. Of course, it will be
student-quality code, if you know what I mean...

If the xemacs on A is running gnuserv, you can do:

gnuclient -q -eval "(make-frame-on-display \"$DISPLAY\")"

on machine B. That will tell A to open the frame on B. You probably
want gnuserv-frame set to t, or else this will pop up *another* frame
on A.

Thanks for the suggestion. However, I'm having these students do
something a little fancier than that. It will allow any number of
people to join an editing group, and will do collision detection (i.e.,
a message saying that two or more of you boneheads are trying to edit
the same part of the document ... as if that wouldn't quickly become
obvious). They'll be doing some performance tuning, etc. It should be
fun, and might actually be useful. :-)

She shemacs project has already done this, but the source is semi-closed
so I don't use it and can't say how good it is.
