Here's an article about how this "X tunneling" is really working (for those of you who care how stuff works under the hood). I agree, NX is totally awesome - amazingly fast. On a related note, if you're trying to help out a relative with their computer, I just tried out Co-Pilot which surprisingly "just worked". It's not really an alternative to NX, but way better for this remote-assist case.

To run qemu to start a virtual machine, on a remote host you need to use the command ssh -Y instead of -X, ssh -X results in an error message without starting an remote virtual machine.

-Y Enables trusted X11 forwarding. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls.

When the sshd server is configured with “X11Forwarding no”, try the following to run remote x xlients:
1. xhost +localhost
2. ssh -R 6000:192.168.2.1:6000 test@ahost
3. On remote ahost export DISPLAY=127.0.0.1:0.0

I can help to say that at least for me, FreeNX from NoMachine has been easy and reliable. I use it a lot from a windows PC and a MacOSX. Configuring a HTTP Proxy is very simple too
