I've tossed the idea of Squeak out to the Portland Area Robotics Society
group list and the response is building up (although a bit sluggish).

One question that immediately arose was whether Squeak is limited to the
"Big 3" OS's or is there a VM for other embedded processors maybe
without OS's.  

The Swiki says Squeak VM's are supported for Mac, MS, RISC and flavors
of UNIX.

I remember reading somewhere that a student implemented a VM on a native
uP as a Summer project.

Has there been much VM development on embedded uP's.

Is there any work on a Squeak OS on any platform?

Thanks for the support!
