The authors have developed a distributed asynchronous web based training system. In order to improve the scalability and robustness of this system, all contents and a function are realized on mobile agents. These agents are distributed to computers, and they can use a peer-to-peer network that modified content-addressable network. 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, as a solution of this issue, they present an e-Learning system that is composed of computers of different participation types. Enabling the computer of different participation types will improve the convenience of the system.
