Is the "WPF Client Profile" packaged seperately from the bootstrapper, so that existing 3rd party installations could simply execute the profile package and pipe it's feedback (similar to how the full .NET redistributable is silently executable)?

The bootstrapper sounds like it will be very useful for new WPF apps where the developers don't yet have the deployment scenario  handled, but for existing apps, a client profile redistributable/package/whatever that could take the place of the existing redistributable would be fantastic..
