I wouldn't go that far - apart from anything else this is designed for
deployment into cellphones and simlar high end systems where you've got
external components to bolt on somehow, and as we're only just starting
to see silicon coming onto the market we'll have to see exactly what
things look like.  This stuff is intended for markets where people bolt
their systems together in very custom ways so automatic discovery is not
a high priority.
