Presence and IntComm WG

[Candace Holman <>]

Dear PICers,

[ACTION] The PIC WG will evaluate what functions (e.g. group chat) should be
added to the next version of the PIC-SER package.

As noted above, one of our outstanding action items is to come up with a 
list of features that we think are worthwhile to request in SER PA 
module, and to have this list available for a variety of reasons:

   * to hone in on direction and drivers for WG projects,
     presentations, and other activities
   * to form initial consensus on the protocols, platforms, and systems
     this WG endorses
   * to be prepared next time a developer is seeking a project idea, or
     there is another similar outstanding opportunity such as Google's
     Summer of Code
   * to evaluate for our local groups what are the important real time
     communications features

To that end, I would like to cordially invite you to help build the 
first draft list by adding to the list below.  Once we have a longer 
list we can then use it to debate the value and priority of each feature 
request.  Some of these were spawned by conversations with PIC-SER 
participants, some are old action items, and some have been mentioned in 
previous discussions on the conference calls.

  1. Benchmark basic functionality with a single client
  2. Benchmark basic functionality and interoperability with several
     clients
  3. IM/SPAM prevention
  4. Jabber gateway, and also whatever the new Jabber is in the future
  5. Video, whiteboards, and other shared visuals
  6. Group chat, such as Message Session Relay Protocol
  7. BEHAVE support such as NAT, STUN, and other protocols to soothe
     end-to-end demons like firewalls and session border controllers
  8. Presence updates via SUBSCRIBE/NOTIFY for clients that don't
     implement PUBLISH
  9. Secure updates, such as via encryption and authenticated
     subscribes, notifies(?), and identities
 10. Privacy measures, such as anonymous IM, and the method for client
     controls
 11. Optimized updates, such as partial presence updates
 12. Automatic presence and capabilities updates, such as recognition
     of added USB device or idle time
 13. Message silo storage while you're offline or updates are
     undeliverable
 14. Ability to login from multiple locations but choose which session
     is valid (UCB)
 15. Enhanced capabilities detection, such as customizable scripts that
     describe resources (MIT)
