Yep, that was my idea, but using the extra typinfo could also do VM
optimizations on a interprocedural level, and as such bridge the gap
to.. say java classes. I felt that the Strong talk idea is cool because
enables optional typing as a special case in a VM, like a seamless
bridge to the typed and word-size industry world.

Wine (windows emulator) seems to handle it fine just up until I start
the mandel-app: err:local:LOCAL_GetBlock not enough space in GDI heap
0147 for 136 bytes. But I trust your word for it. ;-)
I feel quite restrained in using java, but then have to. I have tried to
make it bearable by building a small GUI-Lobby, shared VM (know the
limits) and runtime evaluator (using the class loader). This however is
far from the practical gains of prototyping and I often find myself
starting the ol'Self demo to find comfort in that there might be a
revolution rather than just slow evolution out there.
I have long played with the idea to use Self as the development platform
for java apps, and combine changing live classes in java by modifying
slots. I know this is a ugly round trip in a Self perspective, but in
comparison with todays java-IDE-world, it would be a blessing. It would
require a well integrated concept for types, at least in the IDE. This
method could be used to produce .net, c, etc too, all in the native
language but with fragments of the prototype runtime experience.
If one can't sell prototyping directly in industry apps,
one could at least make use of it in development. ;-)
Any such projects out there perhaps?
