Vista - Remote event possible with WCF ?

Hi,
I'd like to know if i can have this type of behavior :

I have a object "SeverMonitor" which has 2 events "EventA" and "EventB".
When i create an instance of ServerMonitor it will periodically poll a
database and raise EventA or EventB based on some data. I know how to do this.
Now i'd like to make ServerMonitor an Single Remote Object and have client
apps adding event handlers to EventA and EventB and when i raise EventA or
EventB, all clients will be called.
It looks like a duplex contrat but i don't want to have a server object for
each client (PerSession) but a Single server object.
Of course i could use something else as events like calling a OnWay method
to register to an event (RegisterEventA) and my server object will keep a
callback for each client...

Anyone knows if it's possible to have this type of behavior ?

Thanks

Well according to

http://msdn.microsoft.com/winfx/defa...s/default.aspx

"Windows Communication Foundation does not allow you to pass object
references across service boundaries."

So my thought is that even using the Session enabled (PerSession) services
will not enable this kind of functionality. It will however keep a reference
to one instance, so if that instance is doing some polling and the client
runs off to do other work the client could in theory poll that instance for a
change in the situation. Actually in that scenario you might want to consider
the InstanceContextMode.Single ServiceBehavior ... What kind of client to you
forsee needing this functionality ? (web, thick, other application)
