Which distros install from USB/Live USB?

[markw10]

A friend of mine is working at a company that's getting a lot of netbooks. None of them have optical drives so USB is important. They are going to switch most of the netbooks from Windows XP to Linux.
I told him that both Ubuntu and Ubuntu Netbook Remix can be used this way. He installed both to a USB Drive and what he likes is at bootup it gives the option to either run it from USB as a Live Distribution or to install it to the hard drive. The installation would give him a way of switching them to Linux and in other cases for users who prefer Windows XP they still have the option of using a USB Flash Drive when they want to use Linux.
The question: What other distributions work this way? I have looked at Fedora, CentOS, Mandriva, and OpenSUSE. Would either of these install from USB or even work as a Live Distribution from USB or even do both? Are there other distributions that would do this?

You can find a long listing of distros that run from live USB flash drive here:

Boot and run Linux from a USB flash memory stick | USB Pen Drive Linux

I'd think some of them should install to the hard disk as well if desired, but not sure.
