Method and apparatus for resource sharing between a plurality of user devices in a computer network

To solve the problems in prior art, the present invention has provided a new scheme for resource sharing between user devices, which shall be easily used, implemented and extended. Also, the present invention aims to decrease the user input for resource sharing. In particular, the present invention is based on IM protocol, the sharing initiator, and its cooperators concerning the key information of the to-be-consigned tasks via IM messages. Then, preferably, the initiator chooses one or more cooperators for each of the to-be-consigned tasks after further communication with the cooperators. For each task, the chosen cooperators will be referred to as its nominated cooperators. At last, each of the cooperators will handle the task(s) consigned to it, if any, and sends the result back to the initiator.
