a virtual machine

This is a very good start for any Lisp VM discussion. It has the advantage
that several compilers have been built on top of it. This gives it a wide
I believe the LispOS community should start with something like this.
Extend it to subsume the Java VM. Extend it to translate to native binary
efficiently. Keep it simple. Write an easy to read standards document, and
go for it. Create a new, larger commercial market place on the Web.
