Automatic service discovery and inter-service communications in a peer-to-peer network

A first computing device connected to a peer-to-peer network, the first computing device comprising:

• one or more processing units;
• and
• memory storing instructions that, when executed by the one or more processing units, cause the first computing device to:
• receive, from a second computing device connected to the peer-to-peer network, information about a first service that is active on the second computing device;
• store the information about the first service in a registry of the first computing device;
• detect, while the information about the first service is stored in the registry, a request to transmit a first query to the first service;
• in response to detecting the request, transmit, to the second computing device based on the information about the first service, the first query;
• receive, from the second computing device after transmitting the first query, a first notification associated with the first query;
• detect, by the first device, that a second service has become active on the first device;
• in response to detecting that the second service has become active, multicast, by the first device to the peer-to-peer network, information about the second service;
• receive, by the first device from the second device while the second service is active on the first device, a second query associated with the second service;
• identify, by the second service based on the second query, second data that satisfies the second query;
• and
• in response to identifying the second data, transmit, by the first device to the second device, a second notification associated with the second query.

A system, comprising:

• a first device connected to a peer-to-peer network;
• and
• a display screen coupled with the first device, wherein the system is configured to:
• receive, from a second device via the peer-to-peer network, information about a first service that is active on the second device;
• in response to receiving the information about the first service, display, via the display screen, a user interface comprising:
• an indication of the second device,
• at least some of the information about the first service,
• a device selection region configured to receive a user input indicating a selected device, and
• a search string entry region configured to receive a user input indicating a search string;
• detect, via the user interface, a plurality of user inputs comprising a first user input indicating the second device and a second user input indicating a first search string;
• and
• in response to detecting the plurality of user inputs, transmitting, to the second device via the peer-to-peer network, a first query comprising the first search string.
