[PEPr] Comment on RFC::NotificationCenter

Greg Beaver (http://pear.php.net/user/cellog) has commented on the proposal for RFC::NotificationCenter. Comment: I agree with the idea of defining interfaces first, and having a sample implementation or default implementation of this interface. This way, people can count on the same system for event notification, without requiring more code if a package only needs to implement a portion of this. Alan has brought up the idea of getting this pattern into something like SPL before on internals, maybe it is a better time to bring it up again there too, this would greatly simplify Bertrand's excellent efforts. I have also attempted to implement something that would provide more than just notification, but two-way messaging. In my experiments, there was no reason to require the use of an object to encase the message, as the data format was most easily defined/constrained by the message type/intended recipient type. After all, nobody will handle messages that are not intended for them, so who cares what the format is? This provides a tremendous performance gain at the same time that flexibility increases, and results in significantly smaller code. I can unearth my old work if you are interested.
