ssh -X instead of vnc

I noticed more direct access to X11 server is to use "ssh -X" instead of vnc. In other words, to be a X11 client to access X11 server on Pi. It reminds me using Xterminal to access SUN workstation 20 years ago. Although I supposed Mac OSX includes X11 modules, Moutain Lion does not and need XQuartz to be installed. http://xquartz.macosforge.org/landing/

After installing Xquartsz, just type
ssh -X ipaddress

Nothing different from normal ssh first, but once you launch mincraft-pi or other window-based program, you could see the window on the max as well as HDTV output. Strange thing is, you can open X application without window manager at HDTV side.

Then test basic movement of Minecraft, now mouse (in fact trackpad) movement is fine and you can see up by scroll  up on the trackpad. However, you cannot place a block. It needs to click right button, but standard "mac way", clicking with option, control key, does not work.

Maybe there should be a solution....
