    Well, it is the same problem as finding out if a TCP/IP socket is connected 
    a remote system or not.  You can get the remote peer address for the socket 
    and compare that to the local address(es).  If the X connection isn't a 
    socket, then it is local (i.e. Unix socket).

You can do that with an X connection, I guess, since Emacs has the
connection.  What would it do for a tty?  Look at the tty name to see
if it is a pty?

And how do you decide how fast a remote connection is, nowadays?
Lots of them go to a machine on the same local net, and that would
be so fast it might as well be the same machine (as far as Emacs redisplay
decisions are concerned).

We could just treat all terminals as fast unless the user specifies
a slower speed.

Is there some way of measuring the speed of the connection?
With X, perhaps there is: do XSync and see how long it takes.

Any other ideas?
