Here is the initial draft requirements lists for wg-pic to begin 
constructing a longer term  trial package.  Please make adjustments where 
needed.

Draft Requirements for Longer Term PALS Trial Packaging
12/20/04

Introduction
------------
All members of the working group invite longer term trial participation -
hopefully from schools, hospitals, and other institutions that have a
predetermined desire for presence techologies.  However, we realize that it is
difficult to sell the idea of a trial without a package.  This document starts
the process of packaging a presence trial based on current client and server
implementations.

To package a trial when we have to agree on the basic representation of a 
trial. This initial document assumes that we will provide documentation, 
server code, and installation and simulation scripts to potential trial 
participants.

The rest of the document describes a semi-chronological listing of tasks to
support Longer Term Trial Packaging.


Preliminaries
-------------
Agree upon several scenarios for longer term trial deployment - choose from 
each category:
a. Server: I2 PALS server, Local ser/pa server configured by PIC-WG script,
Local ser/pa server customized for local use, Local custom (geopriv-based?)
location server
b. Data collection: HP Skiffs, custom solutions based on APs, manual PUBLISH
c. Data Aggregation:  HP Data Aggregator, custom solutions
d. Client: some possibilities are SIPc, Xten eyeBeam, custom solution
e. Protocol options: XCAP/PIDF, PUBLISH
f. Client modes: IM, rich-presence, sip-voice, gatewayed-voice, and/or video

Research
--------
Determine basic components of an ser/pa install, including:
- configure network settings
- configure access control
- configure user accounts
- configure maps and access point locations (?)

Server
------
Stabilize the current PA version to most recent chosen RFCs/I-Ds
Create bug list, prioritize solutions, enlist help
Ensure the current stable version is available in the ser cvs repository
Create installation scripts for one-button setup

Client
------
Use SIPc for basic IM and Voice if intellectual property rights check out
Find some other clients that use the PUBLISH method for presence/loc updates
Create bug list, prioritize solutions, enlist help

Loc/Presence Aggregation
------------------------
Determine intellectual property rights of current package
Possibly create a middleware system to do RFC3903 (event  stuff
Determine standard map image upload and mapped location tracking requirements

Coding
------
Write script that tests the PUBLISH capability of PALS, confirms local network
viability like a basic echo test
Write scripts that install and configure the ser server

Documentation
-------------
Write a document about presence/location data handling in the PA module
- methods and hardware to publish data
- methods to gather and aggregate data
- how to test virtual location aggregation

Update Jamey's client requirements document
Write a server requirements document
Write an "adherance to current standards" document
