Silverlight

User starts up a silverlight application in their browser by navigating to a given URL.

User then opens another browser and starts up the same silverlight application by navigating to the same URL.

Can the second instance of the application detect that there is already an instance running on the same computer?

Can it detect itself if both applications are running within the same browser instance?

I would expect the answer to be 'no' but thought that i would ask it anyway. Otherwise i believe that i will have to setup a webservice and have each instance register itself and send requests to other instances from the same IP. does that sound reasonable?
