Abstract: Various technologies for sharing digital images within an instant messaging (IM) session between two users. In one implementation, a first user uploads a set of images to the second user. The set of images may be displayed as thumbnails on the displays of both users. By clicking on one of the thumbnails, either user may make the associated image appear as a larger image on both users' displays. In the event that both users click on different images simultaneously, or near-simultaneously, a protocol may be employed that selects which image is displayed.

Abstract: Voice instant messaging between mobile and computing devices is described. In an embodiment, a messaging service receives a recorded voice clip from a mobile communication-enabled device via a wireless communication link. The messaging service then processes the recorded voice clip for communication via a data network to a computing-based device that renders an audio message from the recorded voice clip. A virtual connection protocol manages and sequences transmission control protocol (TCP) connection events to provide reliable wireless transfer of recorded voice clip(s) via wireless communication link. The mobile communication-enabled device logs a first instant messaging contact into the messaging service, and the computing-based device logs a second instant messaging contact into the messaging service to enable two-way voice instant messaging between the first instant messaging contact and the second instant messaging contact at the respective devices.

Abstract: Asynchronous voice messaging is employed to enable individuals to send voice clips back and forth over a network. In at least some embodiments, the voice clips reside in the form of discrete, manageable objects that can be easily managed by the user. In addition, some embodiments described provide hand-free/eyes-free functionality that can permit a user to create and send (or receive and play) a voice message without having to physically enter an intended recipient's address or otherwise digitally manipulate the device over which the message is sent or received.

Abstract: Communication functionality is described for conducting communication among a plurality of participants in peer-to-peer fashion. The communication functionality comprises peer-to-peer overlay functionality configured to establish a peer-to-peer overlay network that includes a plurality of participants. The peer-to-peer overlay functionality relies on endpoint provider functionality for physically exchanging information among the plurality of participants in the peer-to-peer overlay network. The endpoint provider functionality exchanges information using a transport mechanism. The transport mechanism accommodates multiple different transport protocols for exchanging information among the plurality of participants, allowing different pairs of participants to communicate with each other using different respective transport protocols.

Abstract: A method and system facilitating selection of participants in multiplayer online electronic games. The method provides an efficient procedure for players to host and join new instances of multiplayer online electronic games, as well as providing a scheme that enables players to join multiplayer online electronic games that are already in progress. The method is implemented through a gaming utility that runs on each player's electronic device (e.g. PC) and interacts behind the scenes with an online messaging service. Player hosts are enabled to select players from a list of contacts provided by the online messaging service who they want to invite to join a chat session. A selected multiplayer online electronic game is selectively launched on all of the player's computers through a single command issued by the host.
