[Ben Teitelbaum <>]

Attendees:
  - Jeremy George
  - Xiaotao Wu
  - Ben Teitelbaum (minute taker)
  - Art Gaylord
  - Alan Whinery
  - Jamey Hicks

Last Call
  - Small
  - Probably Jeremy discouraged folks by saying he wouldn't be on it
  - In future will send out reminder/draft agenda ahead of time
  - Also, we'll designate a minute taker for this (and future) calls

Columbia Architecture Meeting
  - Dec 2nd, 9:30 - 3:00pm
  - Columbia University, Mudd Building
  - Morning in 453 Mudd; Afternoon in 473 Mudd 
  - Jamey to draft architecture diagram by next week's call; we need
    to review this and arrive prepared!
  - We have 10 confirmed attendees (pretty much at capacity)

East West Center (Hawaii)
  - Jamey and Alan in communications re: floor plans and WiFi
  - Building is old; no AutoCAD available, only paper blueprints
  - Alan will take some measurements by hand

Internet Weather Presence 
  - Ben has re-thought wisdom of requiring participants to download
    special measurement software to get one-way loss
  - Instead, will just use ping (already on clients); actually using
    fping, which generates more machine-readable output
  - Adding new fields to "place" table (downstream_loss,
    upstream_loss, session_name, session_end_time, area); "area" is
    to support location dithering

Per-room Miking
  - Art talking to audio engineer friend and looking at Polycom
    conference phones
  - Alan says the East-West center rooms are heavily miked
  - Alan is on PC and will find out how many different rooms will be
    in use 

Presence Portal
  - Not much has happened
  - HP Labs has developed a graphical display of user location
  - This will be integrated by Joint Techs

WiFi
  - Have complete map of campus APs (channels are hard-set)
  - Access points in East-West center are not yet set up, but Alan
    will find out how the channels will be configured

Location
  - Planning to add SUBSCRIBE/NOTIFY support

Discussion of asymmetric performance, iLBC, and whether session
negotiation supports asymmetric codecs
