Certainly, Mite has been presented at EuroForth.  There is a
difference in focus between portable assembly languages like PAF and
virtual machines like JVM and Mite:

They are both intermediate languages, but VMs like these also have
their own code distribution format and present the program with a
closed environment that allows things like garbage collection on the
VM level, but may be a bad match for many languages (e.g., the JVM is
a bad match for Forth).  In contrast, a portable assembly just
abstracts some differences between concrete machines away for
portability, but otherwise tries to give access to the raw
(user-level) machine.

That seems to be similar in spirit to PAF.  I would have to look
closer at it to make a well-founded comparison.

Yes, I looked at that when writing the paper (it comes up when you
google for "portable assembly language").  It's also a portable
assembly language in spirit, but the focus is on multi-precision
arithmetic (where existing portable assembly languages such as C suck,
and PAF is not much better) rather than on features a language
compiler would use.  Some comments in my paper on missing features of
PAF were inspired by this work.

>I've wondered about using the backend of TinyCC as a JIT

AFAIK The back end of tcc is integrated with the front end, so that
would be quite a bit of work.
