Presence and IntComm WG

[Candace Holman <>]

In anticipation of this week's conference call, Ben and I have been 
discussing some of the advantages of using a presence agent over using peer 
to peer communication.  I question some of the advantages that I came up, 
so please comment on this list.  Also, please add to this list if you know 
of additional advantages.

1. Reduced traffic, more scaleable as number of peers rises

2. Reduced access control administration (traffic comes from single source)

3. Synthesized multi-ua information (presence update merging when multiple 
devices are used by a single presentity)

4. Identity assurance (not strongly authenticated, but some assurance of 
intradomain identity)

5. Centrally managed contact lists and blacklists (not yet in PIC-SER)

6. Partial presence publishing (not yet in PIC-SER, not sure this has to be 
centralized either)

Thanks,
Candace
