I'm sorry. <br><br>I didn't realize I forgot to clarify this point. The server offers services to the clients, but the clients mus offer some services in return, and of course, all of them the same services. Is somethign like this:
<br> One client must stop working so, before that, sends a request to the server, and the server ask to the others clients on the net to do the tasks of the one that is leaving.<br><br>thanks<br>
