A system and method for peer-to-peer datacasting in a broadcasting network is disclosed. The method may include providing first and second peers and a source, wherein the first and second peers are configured to communicate data with the source via the broadcasting network, wherein each of the first and second peers stores an updatable software object, wherein the source stores the most recent version of the software object, and wherein the second peer is configured to communicate data with the source via the first peer. The method may also include receiving, at the first peer, an update request for a software object from the second peer and obtaining, at the first peer, the most recent version of the software object associated with the update request. The method may further include transmitting, at the first peer, the requested most recent version of the software object to the second peer and updating the software object of the second peer with the received software object.
