[jdev] PubSub question

[Remko Troncon]

Hi,

Something isn't very clear to me about the use of PubSub.

Suppose i log in from home with my brand new client, and i want to set an
avatar. My client requests an instant node to be set (as an end user, i can't
be bothered with creating nodes myself), the service gives me a fresh node,
and i start publishing there. A little later, i go to work, install the
same client, and i want to suddenly change my avatar there. How does my
client at work know on which node he has to publish ? Should it create
a new node for himself ? Probably not, since then all the people who saw me 
online earlier and disco-ed me won't know i'm suddenly publishing to another
node. So, how can i retrieve on what node i was publishing my avatar ?

thanks a lot,
Remko
