We have developed a distributed asynchronous web-based training system. In order to improve the scalability and robustness of this system, all the content and a function are realized on mobile agents. These agents are distributed to computers, and they can use a Peer to Peer network that modifies the DHT Content Addressable Network (CAN). In this system, all computers offer the function and exercise by themselves. However, the system that all computers do the same behavior is not realistic. In this paper, we present an e-learning system composed of computers with different types of participation as a solution to this problem. Activating computers of different types of participation will improve the convenience of the system.
