Create USB drive with multiple installers

Hey there!

So I have re-found this 16GB pen drive and have gotten some nice idea. Since I am one that likes to test alot of different operating systems on my mac, I noticed that installing from USB is way faster than from CD - especially because I am using a MacBook air, and hooking up a cd drive isnt always nice.

So I was curios and wanted to ask, if it is possible to put following three copies onto a thumbdrive:

- MacOS X ML

- Windows 7

- Fedora (CD size)

All the three are installers. I thought about installing a bootloader into my pen drive but it somehow didn't work.

Anybody having an idea?
