I've placed PDF copies of all presentations from the IETF-57 BOF meeting on the web link below, so you can down-load them. I'll also place a copy of the minutes in this directory when they are finalised. These will also appear in the official IETF proceedings for IETF-57. http://www.erg.abdn.ac.uk/ip-dvb/meetings/IETF-57-Vienna/ Gorry Fairhurst
