Which would make the project slightly more involved....

There is also a version of Flex that will run natively on the Dragon, 
which is kicking around somewhere, though not sure if it is available on 
the Dragon archive site.

What is available in source form is the source to NitrOS9, which is 
basically a clone of the other big 6809 based os OS-9, this was 
basically a multi-user, multi-tasking os with propper device drivers 
etc, so would be much more suited to running across a tube or tube like 
link.

Cheers.
