XDMCP - Pen Drive Client

[flubbard]

I have a linux box that I would like to use as a server with a couple of laptops or very basic desktops connecting to it using xdmcp. I would like to have the clients be able to boot from either a live cd or a jump drive (to not affect their current configurations) and have them default to the xdmcp signon.

Does anyone know of either a pen drive linux or live-linux cd that would work for this project? I would welcome any other suggestions of how it might be done better, but I would like to limit the purchase of new hardware.

Thanks,
flub
