A friend is asking me which image already relicensed he can use for some project. Is Squeak image 1.1 http://ftp.squeak.org/ the most recent he can use?

Please Georges, can you articulate what you exactly want to do with Squeak related to "physic simulations and physic measurements" ?
Hello Hilaire,
I just want to do very basic things:
We already have three identified methods to achieve physical measurements with an environment of free-libre software:
- using the Comedi library, and the kernel modules coming for approximately 200 different acquisition devices. I currently use the device USB-DUX with this library - using the project Liberlab : it is a lightweight acquisition interface based on a cheap microcontroller, with a free-libre firmware, and free-libre driver written in python. The setup is not produced by a company, but you can easily have a kit and do it yourself - using the devices known as Phoenix, developed by Ajith Kumar and C.E. Pramode: these are produced by an electronic company in India, and are very few expensive. They come with free-libre firmware, and free-libre python libraries.
The projects I saw about Squeak and physics are only simulators : you can play with a physic law and program easily an animation based on it.
I want to add one feature more: giving the students a Squeak interface to drive an acquisition device and get real measurements back in their box. Then these measurements can eventually be compared with simulated results.
This new feature requires _no sophisticated graphic library_, so it can eventually be based on a very early image for Squeak, eventually one image containing only contributions of people having already decided to relicense their work. The question would be: can such an image be found nowadays?
Best regards, Georges.
