Configuration is, as I understand it, pending v1.3 in xAP, so it may end up
similar!

Confusion reigns! in all probability, the config message would end up with
both devices taking on the new ID, and much gnashing of teeth would
follow..

The short version, "extremely simple" is the watchword, and you
have a
little more work as an installer, in return for greater simplicity in
getting to that point!

possibly, but it is a one-time only process.

Yep. It's implied that any device which can be configured has some
mechanism
for retaining this configuration between power-ups.

That's correct, I'll get the document updated.

ditto, again, I'll get the doc updated.

Thanks Keith!
