[Blind-sysadmins] pendrivelinux?

Hello, Is anyone using pendrivelinux: www.pendrivelinux.com to make multi boot thumb drives? If so are the OS's you get accessible, come up with speech? A friend of mine is using this, and he says he uses the YUMI loader, I'm assuming that's a boot loader. I would like to do this myself as I can see the potential in it, but I would like to know which options I'm selecting on boot and then to have the subsequent operating systems come up talking, for example Orca on Linux. If anyone has any pointers or has this working let me know. Thanks. Dave.
