I know this is somewhere on the roadmap, but I thought I'd give you a specific example of how I would like to use this to lookup the Operation List name for a corresponding guid from within a PowerShell script. I know this method exists on the WCF endpoint because it is exposed in the WSDL. However it is not a simple exercise to access this from PowerShell.
For the time being I have a work-around which relies on looking up the Event Broker registry key to determine the extensibility file path, then querying the operations extensibility xml directly. However the limitation here is that this will only work if the script is running locally on the Event Broker service host.
