Etoys-To-Go is a version of Etoys that can run without installation directly from a USB drive. Projects are saved to the USB drive by default. We will make it run on as many machines as possible.
All versions should run on Mac, Windows, and Linux. Get Etoys-version-ToGo.zip from:
http://squeakland.org/download/
Download and unpack onto a USB drive (or a folder on your hard disk for testing). Then double-click "Etoys-To-Go" on a Mac, "Etoys.exe" on Windows, or "etoys.sh" on Linux.
As of Aug 28, 2009 this includes these versions:

VMs: Mac 4.2.1b1 Win 3.11.4, Linux 3.10-3
The main difference between Etoys-To-Go and the regular Etoys is the way it finds the default project directory. In Etoys-To-Go, the projects directory is in the same place as the Etoys-To-Go application. Presumably that is a USB memory stick, so projects are stored on the stick, too, and can easily be transported. In regular Etoys, projects are saved to the user's documents directory on the machine's hard disk, so transporting them to a different machine needs copying.
Another difference is that the web browser plugin requires installation on the user's machine, because the browser needs to find the plugin, and the plugin needs to find the Etoys application. So Etoys-To-Go does not provide a web browser plugin.
