[net.micro.6809] Threaded interpreted language for OS-9

I am giving serious thought to writing a threaded interpreted
language for OS-9 (Coco in my case) for all the usual benefits
touted by TIL enthusiasts: acceptable speed, extremely compact,
very fast "compiler", interactive debugging, etc.  Before I
start, though, I thought I'd ask if anyone else is working on
such a beast.

The following list are the attributes I consider important in
an OS-9 implementation.  Would anyone care to suggest any others?

  - Code is reentrent, hence can take advantage of OS-9
    multi-tasking without multiple copies of the language
    kernal.

  - Code is position independent, so OS-9 can load it wherever
    it pleases.  Similarly, data space for a dictionary, variables,
    etc should be obtained dynamically.

  - Uses the standard OS-9 file system.

  - Provides access to many, if not all, of the OS-9 system
    calls.

A straightforward implementation of FORTH, for example, fails
most of these.

This is a non-trivial piece of coding, so again, is anyone else
working on such a language for sale or public domain distribution?
I'm willing to pay some reasonable price rather than re-invent
this particular wheel.
