I will reach out to Qualcomm to discuss options here.  We can
certainly offer to mentor, and I think we might even be able to
take over the work.  But I won't be able to get any resolution
on this until next week.

Jie Luo, please hold off on further posts on this for a little

I will report back once I've been able to discuss this with
folks at Qualcomm.
