Have you seen anything prior to Sept 26, 2003 which relates to Programmable Proxies for Determining a Presence Status of a User:
A method comprising:
Obtaining presence information from a plurality of presence data stores, wherein the presence information provides a clue as to a presence status of a user;
Translating the presence information into a standard format, yielding translated presence information; and
Determining the presence status based on the translated presence information.
It seems to me that Voxhub has prior art. For example, the Herenow engine.
