That's great, they're making it even more convenient for people to give the system a try. The majority of people still don't realize that Linux can power a very capable and easy to use system for the desktop.
I recall that someone else was doing this years back - who was it? I think the company that developed Nautilus originally, Eazel.
I went to high school where there was an Edubuntu lab. Each PC had a local OS, but it also booted off of a server in the corner via LTSP, giving everyone a portable Gnome environment.
With this, a class could have access to that environment on any machine without having to boot to NIC. This has potential.
