[JDEV] How to find the presence of a user at server side (was

[CORVOYSIER David FTRD/DMI/REN]

That's a very interesting feature indeed ...
Has anybody already thought about using this bcc system to store the
presence in a dedicated module (apart from the JSM) in order to perform
advanced queries on all the connected users (for example, combine it with a
search)?
My concerns about this kind of solution would be:
1) the induced traffic overhead
2) the synchronization issues that may occur when that module or the JSM
fails

Any thoughts would be appreciated ...

In 1.4.2 you can configure jsm with a
<presence><bcc>servicename</bcc></presence> (multiple bcc elements, and can
contain any jid) which will blindly carbon-copy the bcc'd address with every
users presence change.  This also validates that address as one that can
presence type="probe" a user of that jsm and get the available presence at
any time.

Should be useful for building web and presence gateways (wcs can display
such presence on the web) or administrative tools...
