fredj, I like the idea of having operationstarted and operationfinished type events. But I'd go with a different implementation. Not to clobber the base class and modify every Protocol class I'd implement a decorator class, for example named OpenLayers.Protocol.TriggerEvent. This decorator class would be responsible for triggering the events; instances of this class will be configured with a protocol.
