Abstract: In one embodiment, a method includes receiving a request to send data to a client device of a user. The method includes determining a first subset of the data for sending to the client device of the user and a second subset of the data for storing at the computing device. The second subset of the data correspond to a portion of the data for subsequent downloading by the user. The method also includes sending the first subset of the data to the client device of the user. The first subset of the data when received at the client device includes a link to download the second subset of the data from the computing device and the second subset of the data when downloaded replaces a portion of the first subset of the data.

Abstract: In one embodiment, a method includes receiving a request to send data to a user. The data exceeds a message size limit of a delivery channel associated with the user. The method also includes converting the data into a number of messages that each conform to the message size limit; and sending the number of messages through the delivery channel.

Abstract: In one embodiment, a method includes receiving a request to share with a first user a content item associated with a second user. A content location for the content item may be determined. A geo-fenced area for the content item may be determined, the geo-fenced area including the content location. The content item may be shared with the first user as requested. If the second user moves to a location outside the geo-fenced area, determination is made of whether the sharing of the content item should be terminated.
