[JDEV] Annotating user's presence with extra information

[Henry Minsky]

I am working on a project where we have a server that is tracking users' 
locations
via various technologies, and recording them in a realtime database.

I would like to be able to annotate each jabber user on the server with
some information about their physical location. This information would most 
likely be
retrieved in the presence information for each user, although might there
be some better place to put it, such as a new separate iq query?

Note that the clients themselves do not necessarily know their own locations,
that information is derived on the server, so I need my "location server" to
somehow inject the location information for each user into the jabber
server, where it can be accessed by custom clients, or perhaps also stuffed
into the english-readable status strings, for backward compatibility with 
existing
clients.

Anyone else working on something like this?

Thanks,
