Tethering has the advantage that the text interpreter runs on a PC,
while the target processor only needs a tiny address interpreter, or
even just a boot point to jump to native code produced by the compiler.

What are the disadvantages?  What are the main difficulties of
implementing a tethered Forth, compared to a regular one?

Is it normal when using one, to develop against the target from
beginning to end, or do you code on a desktop environment first (other
than parts that twiddle the target hardware intensively, and even that
can use emulations)?

This is the type of target I have in mind:

It's an AVR Tiny with 8k of flash and 512B of ram.  But even smaller
targets (say 1k flash / 128B ram) are also interesting.
