You could code around it at the shell level, giving your users a 'smark.sh' script that exposes a Unix like command line interface and hiding the actual invocation of the vm and image. But that would only cover Linux and Mac OS X I guess. On the other hand, Windows is quite different at the command level, so it would be hard to make all this totally transparent.

I think most Smalltalk user would be happy with a 'command line interface' at the Smalltalk level.
