[jdev] Syncing a user's status across many clients

[Thompson, David]

Hello all,

This may be a bit unconventional for XMPP, but is there a reasonable
way to synchronize a user's status across all clients?  When one
client changes their status from 'chat' to 'dnd', the other client's
should change to 'dnd', too.  Additionally, when the user logs in from
yet another location, it should also pick the 'dnd' status.

I wrote a quick hack to sync the status for clients that are already
connected, but I'm struggling to choose the right status when a new
client connects.  I thought that I could just send a presence probe
but the request was not authorized because users are not in their own
roster.  Would simply adding the user to their own roster and using
the presence probe be an acceptable solution?

Are there any other options available?  Am I completely crazy? :P

Thanks,
