I'd agree with this if the hobbyist's goal is to get some gadget working
using Forth as a development tool like an oscilloscope, whose internals
they don't really care about.  If their interest is in language
implementations and Forth hacking per se, obviously not having source
code is a big drawback.

Does that include the target-resident interpreter that will run on
Juergen's board?  I can understand if it doesnt, but it becomes a lot
more interesting if it does.

Agree.

From seeing the huge Arduino world based around the AVR8 when they could
perfectly well be using Cortex M processors, I have to infer that code
speed (and therefore compiler optimizations) just plain don't matter for
a lot of embedded applications.  So from that perspective, I'd say the
attractions of VFX compared to something like Mecrisp are

     1) language features and libraries
     2) umbilical debugging; and
     3) optimizing compiler

in about that order, maybe with 1 and 2 switched.  I do think you'd
generate considerable interest in VFX Lite if you did an AVR target.  I
wonder if the introduction of the MSP432 (a Cortex M0 core with
MSP430-like marketing) means TI now sees the MSP430 as a dead end.  But
the AVR is still going strong.
