There are known GCM based develo= pments underway, but at a telechat held yesterday to discuss this ID it be= came apparent that no one participating in the chat was aware of ANY use of= CCM in SRTP. Hence it was suggested we purge CCM from the current ID =20 This is a call to the mailing list to see if anyone is aware of any concret= e existing projects underway that use CCM mode in SRTP. If there are none,= CCM will be eliminated from the current ID.=20 (Note that if at some date in the future someone wishes to deploy CCM in SR= TP, a simple cut and paste from previous drafts of the current ID can be us= ed to craft a new CCM only ID.)
