You're right. Let's say that the first line was for ssh users and the second
for telnet users :)

And what ? The point of the op was that it was "impossible" to play a
graphical roguelike that way. I just said that it was indeed possible and
even very easy when you add a X server on your current computer. You'll
note that the distant computer has to be a Unix-like system for you to
connect through ssh and play a curses game.

For better of for worse, it's unsafe to assume that a significant number of
players will want to play the game on a distant computer.

Makes me laugth when you talk about broad appeal for a feature none of us
even know if it is used by more than 0.1% of roguelike players.

And btw, you'll note that you can do that with VNC too. And know what ? It
works ok even with somewhat limited bandwidth and it can be used with *any*
kind of computer at both ends of the communication. It's just a little
harder to setup.

It's safe when I control both endpoints of the comunication. It's safe
enouth for me and if that isn't enouth for you, I suggest that you should
pull the plug on your internet connection now before the hackers attack.
