How do you feel about your message now, one year later? I am interested
in pretty much all of the things you discuss in the message: in
particular, in gaining a clearer understanding of the interaction
between a hosting and the hosted system: the VM and image, if you like,
or recursively, processes in the image and the InterpreterSimulator'd

assembling some code and running it.

This is the only one of your list that's low-hanging fruit, really, if
you don't mind poking at the VM sources a bit that is. A primitive for
getting the system to set %eip (%rip) to the start of a given ByteArray
would do the trick ;-)

Perhaps Alien will help here?

These, to me, are (still) *excellent* requirements for a Smalltalk of
the Future!
