USB booting :: Multi-linux, multi-boot USB stick?

I've been dinkin' around with DSL. And Puppy. And Feather/Feather-weight. And Slax. And... and... and...

I am using two USB memory sticks, and I am thinking that I should be able to get more than one Lin OS on a stick, if I can find a way to "steer" it at loading. I have looked at Grub and Lilo, but don't understand what I would have to do to make them go after different Lin OSs... my amateur mods to Lilo didn't accomplish anything other than booting into the original.

So... ideas?

Multiple partitions on a memory stick, each w/ it's own MBR? I don't think that can happen, can it?

I think somebody had a similar idea for putting many, many Live CDs on a DVD and letting the user chose which to load at boot up.

Anybody? Beuhler? Beuhler?

I'm using suse 9.3, DSL-2.1b and DSL-2.3 on 1 HDD. I use DSL GRUB Frugal Install. This thread may help you.
