DSL Embedded :: USB embedded/bootable?? can you have both

Ill start off with telling you what im trying to accomplish.

I want DSL on a USB drive, with the ability to both boot and run as embedded. I want to be able to boot off it for better functionality and speed, but also be able to just throw it in on any xp comp and launch my same OS as teh bootable. Im having alot of troubles figuring out how to do this, is it even possible. If it isnt does anyone have any suggestions for a work around, or how to get it as close to this functionality as possible. Hope this makes sense, I want to be able to access my computer in windows on school comps and my gfs comp without disrupting windows, but also be able to boot off it at home for better function. Thanks for the help
