<p>The invention is directed to a method comprising intercepting a download request, originally directed to an original destination (402), for content; processing the download request; searching for the content in a local cache (423); servicing the download request from the local cache if the content is found in the local cache; forwarding the download request to the original destination if the content is not found in the local cache; and notifying a server (402) of the intercepted download request, wherein the server transmits the content to one or more clients via one or more video channels. The invention is also directed to a method comprising listening for requests from a client (421); receiving, from the client, an intercepted download request for content; managing the amount of available bandwidth in one or more video channels; encapsulating the content in a format suitable for video channels; and transmitting the content to one or more clients via one or more video channels.
