| abstract |
A method for allowing information to be exchanged between a local host and a remote host even if no required software has been prepared in advance. A local host (1) requests a service management host (4) for a commencement of a desired remote service. In response to the request, the service management host (4) selects remote hosts (2) capable of sharing the remote service with the local host, and transmits information concerning the selected remote hosts (2) back to the local host. Based on that information, the local host (1) selects a remote host (2), with which the remote service is desirably shared, and then instructs that remote host (2) to download from the service management host (4) a software for sharing the remote service. Then, that remote host (2) downloads the instructed necessary software from the service management host (4). |
