Launching LiveCDs with Qemu

I've just come across another solution for launching LiveCDs without burning them.
You can use Qemu (which is preferable because it's OpenSource).
To install it is easy: you can do this with apt-get in your konsole:

sudo apt-get install qemu

To launch the live cd just type into the konsole:

qemu -cdrom YOURLIVECD.iso

Easy, isn't it?
