No, I disagree... expose as names elements of the architecture is a bad choice.�
bad marketing to choose ugly names, just for the sake of our techie guys (my self included :P)
the unique official VM for pharo will be called Pharo, and it will be a Cog VM with our additions.
we also will provide another supplementary VM (the StackVM, with a suffix, to accomplish 2 thins: make clear that is not the official, and provide information about why is there). It will be there because is more portable and more stable (for now, we hope to have same stability with the cog soon).�
We don't need two suffixes, just one, because the official vm is just one.�
