Most of the mainline Squeak's don't require install. Grab one and put
the files on the stick.

I always work using a one-click distro, which on a USB key allows you
plug the key into a Linux, Windows, or Mac machine and continue
working against the same image.

I just set up my two sons with usb keys to work like this. They both
run Linux, but they have friends on mac and windows. I used the
Seaside one-click experience, but since we are working through the
Robots book, we just replaced the image and changes file.

There are three text files that point at the image name (one for each platform):

squeak.ini (Windows)
squeak.sh (Unix)
Contents/info.plist (Mac)

Or you can rename your image and changes to match.

I believe Bert is to thank (or someone else from the Plopp team) for
this particular innovation. It is one of my favorite Squeak features
and use it heavily when I attend user groups for Java or Ruby. (I
suppose a Ruby or Java distro could do something similar, but they
certainly wouldn't have a cross-platform image.)
