Presence and IntComm WG

[Candace Holman <>]

(Thanks to all who responded.  I have reorganized and updated the list 
quite a bit with additions, so please review and reply to the list with 
strong objections.  Otherwise, this list can be posted as is as a new 
document on the website.  The original list is archived: 
https://mail.internet2.edu/wws/arc/wg-pic/2006-02/msg00003.html)

The PIC WG has composed a feature list for presence integrated 
communications software.  The list is grouped by categories, but  
neither categories nor features are in priority order and may conflict.

This list serves a variety of purposes:

* to hone in on direction and drivers for WG projects, presentations, 
and other activities
* to be prepared to furnish feature requests to developers and organizations
* to evaluate presence integrated communications features for our local 
groups and Internet2

User Features

* Calendaring, location tracking, personal status/availability/mood, and 
other rich presence
* Voice, conferencing, voice mail, and other audio
* Instant messaging and other shared text
* Video, whiteboards, and other shared visuals
* Default configuration to provide a modicum of privacy and easy 
introductions to all features
* Client control of presence capabilities and notification features
* Automatic presence and capabilities updates, such as recognition of 
added USB device or updates based on idle time
* Enhanced capabilities detection, such as customizable scripts that 
describe resources (MIT)
* Ability to login from multiple locations but choose which session is 
valid (UCB)
* Message silo storage and call-me-back's queued while you're offline, 
with interactive bot agent notification
* Separate the message composition from delivery method (SMS, MMS, etc)

Protocol Specific

* Traversal techniques such as TURN, STUN, and ICE to make SIP/SIMPLE 
behave with NAT, firewalls, and SBCs
* IPv6 implementations
* Group chat, such as Message Session Relay Protocol
* Optimized updates, such as partial presence updates
* Presence updates via SUBSCRIBE/NOTIFY for clients that don't implement 
PUBLISH
* Human readable client/server or client/client transactions to assist 
troubleshooting

Security and Privacy

* Authenticated instant messaging and SP** (SPAM,SPIM,SPIT) prevention
* Secure updates, such as via encryption and authenticated transactions 
and identities
* Privacy measures, such as anonymous IM, and accompanying methods for 
client controls
* Shibboleth authentication integration

Standardization

* Protocol-agnostic (SIMPLE, XMPP, hybrids, and future protocols that 
show forward progress in building and demonstrating working models)
* Devise/implement a benchmark for basic functionality with a single client
* Devise/implement a benchmark basic functionality and interoperability 
with several clients
