003 Source Specific Multicast

I am not fluent in any foreign languages. I have worked with many EOSL speakers and writers. This speaker needs to practice his English as there are many of his words are barely, if not entirely 'swallowed' in attempts to speak such words as 'specific' and 'Rendezvous'. If he slows his delivery by about 20%, I'd guess that would help understand ability and his speaking skills.
