  • receiving, at a first device, service information for a streaming service provided by a second device, the first device and second device being on different first networks, the first networks being different local multicast networks;

    receiving a request to share a display of the first device with the second device;

    inserting an entry in a multicast domain name system (mDNS) cache of the first device based on the service information such that the streaming service is (i) discoverable by the first device via a mDNS query and (ii) accessible through a second network that interconnects the first networks, wherein inserting the entry is conditional based on an acceptance of the request; and

    sending streaming information from the first device to the second device through the second network for the streaming service.
