Abstract: Techniques are provided for delivering messages to users of client devices in a network. At a server device in a network, location information of each of a plurality of client devices is obtained. Each of the client devices runs a presence application for a user in the network and is configured to log-in with one or more resources. A message is received from a sender device in the network. The message is intended to be presented to the user via the presence application and one or more of the resources. Based on the location information of the client devices, one or more designated client devices are selected to which the message is to be sent such that the message is presented to the user via the presence application running on the one or more designated client devices and via one or more of the resources.

Abstract: In one embodiment, a method includes establishing a communications session between a first endpoint that displays a shared desktop and a second endpoint that has a display screen, identifying an active region that is part of the shared desktop, and providing an interface on the second endpoint that obtains an input that indicates whether a representation of the active region is to be automatically displayed on the display screen. An input is obtained, and it is determined when the input indicates that the representation is to be automatically displayed on the display screen in response to the input. If the input indicates that the representation is to be automatically displayed on the display screen, the representation is displayed on the display screen. The representation is automatically displayed on the display screen such that substantially only the representation is displayed on the display screen.

Abstract: In an example embodiment, a virtual conference is established with a server and a plurality of endpoint devices. One endpoint device, acting as a sender, may transfer a file to N other endpoint devices, acting as receivers. The sender divides the file in at least N segments and delivers one segment to each receiver. Receivers then request the next desired segment from one or more devices containing that segment. If devices hold the segment, the segment may be divided into parts, and one part may be requested from each device.

Abstract: In one example embodiment, a method is provided and includes monitoring a display status associated with a client device that is participating in a meeting being conducted over a network (wired, wireless, etc.). The method also includes reporting the display status to a server associated with the meeting. For example, the server could be responsible for controlling at least a portion of meeting resources for the client device (or the client device itself could include software to perform these management functions). The method also includes receiving reduced meeting resources based, at least in part, on the display status.

Abstract: In a sharing session between a presenter and several attendees, the presenter can share any type of document quickly and without substantial prior preparation. The presenter's device identifies an active document-sharing window within the desktop sharing environment, and detects if there is a shared document in the active window. The presenter's device creates a framework for any detected shared document that is transmitted to each of the attendee devices. The framework contains information about the pages in the shared document, such that an attendee device can request a specific page in the shared document. At least the first page of the shared document is rendered to a page image and transmitted to the attendee devices. Upon request from an attendee device, page images of any of the remaining pages may be sent to the attendee device, allowing each attendee to view a different page than the presenter.
