I dont expect this within the 'near' future and as you say existing apps
(may) need code changes. The existing main developers are aware of it
though and (I hope) have a changeover option. It may help if we
released the new UID format I guess. There are some possibilities for
the devices that don't use >254 sub addresses to be mapped back to the
shorter UID's so some backwards compatabily could be achieved, and new
format hubs might be able to translate on the fly. The outgoing xAP
messages go direct and not via a hub though. I will have a chat with
the specification group.

I would code to the existing spec.
