RE: Methods to EventForwardingFactory

I agree, that's definitely the downside of having a String reference to a
first class Event object. The other issue that I wonder about is the whole
event registration thing - right now, when you specify an event factory, you
have to also tell the event broker that you are interested in it (or at
least, whatever consumes it does).

Srinivas, can you give us more information on exactly what you are trying to
accomplish here? That way maybe we can think of alternative approaches, if
they might be more applicable.
