4. 4 Media Guide draft-phelan-dccp-media-00.txt (http://www.phelan- 4.com/dccp/draft-phelan-dccp-media-00.txt) Issues, how-to, benefits for streaming media apps 50+% recap of mailing list discussion 50-% new material Higher level (app viewpoint) than current UG My motivation – why use DCCP, but needed to go through how to get there

5. 5 Way Forward? Build on media guide Add more app stories Need comments on current content Particularly the network behavior sections Need input from other apps Gaming, telemetry, state exchange … Comments on other issues to cover CCID2 vs. CCID3 (which is right for my app?)
