We have long talked about wishing to be able to take advantage of any available L2 mechanisms.  We can't be dependent on them, but we should be aware of what mechanisms might be available, and design our protocols so that they can be used when available.  This would include multicast, and I think would include cell broadcast.

I certainly agree that there is no relationship between ATOCA and PWS or CMAS, but cell broadcast is not exclusive to PWS/CMAS.  

I don't think we need any liaisons at this time.  I think we need to learn how cell broadcast works.  I don't care who we learn it from.
