Presence and IntComm WG

[Candace Holman <>]

Dear PICers,

This is the second and final time that I will send this out.  I've made 
changes, so please re-read and reply with any additions or clarifications.

[ACTION] The PIC WG will evaluate what functions (e.g. group chat) should 
be on our wish list for presence integrated communications software.

We would like 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 enumerate 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 and the community at large 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.  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. Authenticated IM and SP** (SPAM,SPIM,SPIT) prevention
 4. XMPP, and also whatever the future XMPP is
 5. Video, whiteboards, and other shared visuals
 6. Group chat, such as Message Session Relay Protocol
 7. Middleware support such as NAT, STUN, and ICE 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 accompanying methods 
    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)
16. Shibboleth authentication integration
