Hmm. I think I would prefer to receive your stamp of approval before I
commence testing :-)

Overall, if we can achieve the same capabilities as bbv1 for v1.34 I
will be happy - anything extra will be a bonus. My main concern is that
we start off down a road that will allow us to develop the potential
offered by QNX. IMHO a quick port of v1 would not give us that flexibility.

What is the best way forward?
