There is a chapter called "Extending the Squeak Virtual Machine" by Andrew C.
Greenberg in the Book "Squeak: Open Personal Computing and Multimedia" (ed.
Mark Guzdial & Kimberly Rose, ISBN 0130280917), which deals with the issue
of implementing plug-ins and primitive functions.
A preview version is availabe online at
http://www.iam.unibe.ch/~ducasse/FreeBooks/CollectiveNBlueBook/greenberg.pdf
The book is still on sale, though, I believe.
