Jens,

First of all the idea seems cool but I am wondering whether we need a new
type of a proxy for this, because Upul is writing an Atom mediator and we
should be able to extend that to meet these requirements.

I am sorry. I didn't get this aggregation part, why do you think it is a
must to aggregate the answers, I cannot imagine an aggrgation here.

Well, we can define a special type of a control message to the atom mediator
so that those control messages will not be published but will be used to
subscribe users to the atom instead, WDYT?
