I decided to do a strange, but potentially very nifty thing, and share memory between two or more squeak applications on the Mac, but I find I can’t even get started…

What I’d like to do is manually set the pointer for a Bitmap in Image A so that it points to the same shared memory as the BitMap in Image B (and C and D and…)
and then display the Image Bitmap while B (C, etc) asynchronously draw into the same shared memory.
The immediate usecase would be doing a multi-process Mandelbrot Set drawing app where the Image A is for display and menu selection while the remaining Images 
do the calculations and setting of pixels.
Is this doable out-of-the-box in Squeak, or must I write a plugin first?
If so, what do I need to do?

If I do need to write a plug-in, how do I do it. I’ve read on the wiki about the Surface Plugin, but not quite sure if that is what I need or not.

Thanks.
