In 2015, the J9 team announced the plans to open source the platform underlying their JVM implementation. As part of their JavaOne talk “What's in an Object? Java Garbage Collection for the Polygot”, they used SOM++ as a case study to show how their garbage collector can be integrated into an existing VM.
SOMNS, a Newspeak variant with full support for actor concurrency was developed as a platform for research on the interaction of concurrency models.

SOM was used by Michael Haupt between 2007–2009 to teach a course on Virtual Machines at the Hasso Plattner Institute in Potsdam. Many of the feature variants of CSOM for instance support for Smalltalk images, threads, and garbage collection have been developed as part of course work. (more)
In 2006, SOM was used by Michael Haupt to teach one undergraduate course at Lancaster University (UK).
Related to SOM, at least in syntax and spirit:

Revolutionizing Embedded Software
Master's Thesis by Kasper Verdich Lund and Jakob Roland Andersen
SOM was originally implemented at the University of Århus in Denmark by Jakob Roland Andersen, Kasper Verdich Lund, Lars Bak, Mads Torgersen, and Ulrik Pagh Schultz in 2001/2002. It was used for teaching object-oriented VMs and came with the original version of the SOM Smalltalk libraries, test suites, and benchmarks.
