If your device can remember it's instance in non-volatile ram (or whatever)
that's fine, if it can't it needs to either a generate a unique instance or
you can only have one on a single xpl network.

E.g.

An OSD starts with instance of 'default' gets set to 'LOUNGE'
(aec-tvosd.LOUNGE)

A 2nd OSD starts with instance of 'default' gets set to 'BEDROOM2'
(aec-tvosd.BEDROOM2)

So far, so good - but

If you turn off the power to both OSD's and switch them back on and they
_both_ restart with an instance of 'default' (aec-tvosd.default) how does
xplhal know which is 'LOUNGE' and which is 'BEDROOM2'?

If they both remember that they were 'LOUNGE' or 'BEDROOM2' then everything
is fine.
